President Donald Trump has repeatedly criticized U.S. European allies for their alleged failure to assume a larger share of the responsibility for NATO deterrence and defense. Although most U.S. angst about European burden sharing concerns preparedness for a larger conventional war on the continent, the sharing of risk with respect to nuclear escalation has received less attention. Past practice suggested that the American nuclear umbrella would suffice to deter Russian threats of nuclear escalation. On the other hand, Europe’s indigenous nuclear forces may have the potential to serve as a sufficient deterrent against Russian nuclear first use.

French “Forwardism”

In March 2026, French President Emmanuel Macron announced a doctrine of “forward deterrence” regarding the future of French nuclear declaratory and employment policy. His statements amounted to the most important shift in French nuclear posture in decades. The more important components of this policy change are as follows: First, France will increase the size of its nuclear deterrent force (force de dissuasion) for the first time since 1992. The assumption behind this move is that the current nuclear force is too small to deter aggression beyond France’s borders. Second, France would permit the temporary deployment of nuclear-armed aircraft to allied countries. However, France will not delegate nuclear employment authority to other countries. Stationing nuclear forces outside France will reinforce France’s commitment to its European partners. Third, France would work more closely with allies to develop shared understandings of the nature of the Russian threat and to coordinate on the management of escalation control in the context of a conventional war. The first stage of this collaboration will include visits to strategic sites and/or joint exercises with Germany, the UK, and other NATO countries.

Trump’s Frustrations

The decision taken by Macron reflects a perceived need for upgrading the proficiency of France’s nuclear deterrent. It also represents a political statement about his doubts regarding the U.S. commitment to NATO. Despite improvements in European defense readiness and preparedness, President Trump has continued to disparage NATO as weak and “free riding” on the backs of the U.S. military. Trump has announced that he plans to remove 5,000 American troops from Germany and has suggested that the U.S. should leave the alliance despite being prohibited by Congress from unilaterally doing so.

There are several prompts for this continuing cold shoulder from Washington to Brussels. First, Trump is frustrated by Putin and Zelensky and their inability to negotiate a cease-fire and peace agreement between Russia and Ukraine. Second, the U.S. President launched a pre-emptive combat operation against Iran on February 28, 2026, without either consulting or informing NATO allies before the fact. Understandably, in this regard, European leaders have been hesitant to provide military support, and some have refused to grant access to American bases or airspace for Operation Epic Fury, further frustrating President Trump. Third, the stalemate in the Strait of Hormuz has disrupted global supply chains and driven up the prices of fossil fuels and fertilizer worldwide.

European and U.S. Support for Ukraine

Despite distractions, NATO members remain committed to supporting Ukraine as long as needed. An agreement allows U.S. allies in Europe to buy weapons from the U.S. and pass them to Ukraine. The U.S. continues to upgrade its nuclear deterrent, especially the strategic nuclear triad, with a $71.4 billion FY27 plan for next-generation intercontinental ballistic missiles, ballistic missile submarines, strategic bombers with new Long Range Stand-Off (LRSO) missiles, and improved nuclear command and control.

It is doubtful that France’s nuclear force, which includes several hundred warheads with delivery systems such as submarine-launched ballistic missiles and both land- and sea-based aircraft, can replace the U.S. nuclear extended deterrent – nor was it meant to. Instead, France’s independent nuclear deterrence, designed to defend its own interests and sovereignty, along with the United Kingdom’s small ballistic missile submarine force, offers a minimal deterrent against nuclear threats from Russia at a level below strategic nuclear weapons.

Since the beginning of Russia’s war against Ukraine, Russian President Vladimir Putin has repeatedly reminded international audiences that Russia, under certain conditions of adversity in conventional war, might resort to nuclear first use of non-strategic or theater nuclear weapons (NSNW). These weapons, having shorter ranges and lower yields than strategic weapons, can be launched from land, sea, and airborne platforms and could number as many as 2,000 in Russia’s available inventory. In comparison, the U.S. deploys some 200 available NSNWs at several NATO bases.

U.S. Nuclear War Planning and NATO

This disparity in the number of NSNWs is not as alarming as it might seem because the nature of U.S. nuclear war planning has changed since the Cold War. Current U.S. operational plans include the full spectrum of nuclear and conventional kinetic and non-kinetic capabilities within one comprehensive plan. U.S. nuclear forces are expected to provide options for graduated escalation and flexible response. Toward that end, U.S. bomber deployments and military exercises provide additional support to U.S. European Command, bolstering NATO deterrence. In addition to the increased bomber presence, the Trump administration wants to add the flexibility of the nuclear sea-launched cruise missile (SLCM-N) for the deployment of weapons with variable yields. The purpose of SLCM-N is to deter limited nuclear use by adversaries and to provide reassurance to U.S. European and Asian allies.

France recognizes that deterrence is not only about the size of military forces, including nuclear arms, despite Macron’s plan to increase the number of French nuclear weapons. It also depends on perceived resolve among allies and potential adversaries. In Macron’s view, Russia should not expect that democratic Europe can be intimidated by threats of limited nuclear war because (in Russia’s mind) that threat is more realistic compared to strategic nuclear war. Nor should Russia expect that French support for NATO excludes the possibility of deploying French nuclear-capable launchers outside French national territory. French training exercises with NATO countries closer to Russia’s border will help send that message.

Conclusion

A more forward-leaning French military doctrine does not mean abandoning France’s commitment to European security. Nor does it replace the U.S. nuclear deterrent. Macron recognizes that, in defense matters, truth counts more than words: the United States cannot completely detach itself from NATO, nor can NATO sever its ties with America. NATO without the U.S. invites nuclear coercion upon Western Europe, while the U.S. without NATO risks political and military isolation instead of credible deterrence. The American and European pillars of NATO, as the French might say, are “condemned to succeed” together.

Trump Wants NATO Allies to Step Up-Can France Lead the Way was originally published on Global Security Review.

Consider his transformation since February’s Oval Office meeting with Ukrainian President Volodymyr Zelensky. Trump and Vice President JD Vance chastised Zelensky for being “disrespectful,” admonished Zelensky’s efforts to rally international support as “propaganda,” suggested it was Zelensky’s responsibility “to end the destruction of your country,” and described Zelensky as “buried.” Six months later, Trump is praising Ukraine’s “unbreakable spirit,” supports its “future as an independent nation,” and appears to realize that Zelensky is not to blame for Vladimir Putin’s war. It is clear that Putin is not entranced by “the art of the deal,” and that America must play a role in securing any postwar peace. The outlines of that peace are starting to come into focus.

Lurching

In early 2025, French military commanders floated the possibility of forming a “coalition of the willing” to send troops to Ukraine. Other North Atlantic Treaty Organization (NATO) members expressed support for the idea. By summer, 10 European nations offered to contribute troops to a 30,000-man “reassurance force” in postwar Ukraine. However, the Europeans emphasized they would need the US to provide “backstop” capabilities.

That was a nonstarter for Trump—at least until the hastily-arranged summit that brought the leaders of Britain, France, Italy, Germany, Finland, Ukraine, NATO, and the EU to the White House on August 18. Whether they came out of panic over the unsettling Trump-Putin Alaska meeting or in solidarity with Zelensky, or both, the result of the White House summit was positive.

For example, while Trump emphasized that he would not deploy American ground forces and explained that “European nations are going to take a lot of the burden,” he added, “We’re going to help them…we’ll be involved” in any peacekeeping mission.

Toward that end, he ordered Chairman of the Joint Chiefs of Staff General Dan Caine to work with allied militaries on the specifics of a European-led peacekeeping force. Perhaps with the US shouldering command-and-control responsibilities; offering American airpower and other enabling capabilities; and signaling support for a security guarantee for postwar Ukraine, peace may prevail. Predictably, administration officials then hedged on Trump’s promise to support the postwar peacekeeping mission in Ukraine—prompting a NATO diplomat to conclude, “The US is not fully committed to anything.”

What Trump’s transatlantic counterparts and those of us who are critical of Trump’s policies need to keep in mind is that this lurching, two-steps-forward-one-step-back approach to Ukraine’s security is better than what Ukraine endured between January and July. There was the Oval Office meeting, the suspension of military aid and intelligence-sharing, the mineral deal, the moral relativism, outright moral inversion, and the inexplicable deference to Putin. Trump now appears to be moving in the right direction.

Lessons

Zelensky made clear that Ukraine cannot sign a peace deal without concrete security guarantees—given Putin’s brazen violation of the Budapest Memorandum in 2014 and 2022. Eleven years of occupation and war have taught Ukrainians that words are not enough to ensure their security. A genuine security guarantee, bolstered by multinational peacekeepers and sustained military aid, is what Ukraine needs going forward—not to roll back Putin’s army to pre-2014 borders, but to deter it from another landgrab. The rest of Europe needs this too. A strong, stable, secure Ukraine will only enhance NATO’s ability to deter Moscow.

Such a guarantee will not be embodied by Ukraine’s accession to NATO—at least not anytime soon—but instead will be a thatch of bilateral commitments from individual NATO members and partners. “A group of now 30 countries, including Japan and Australia, are working on this concept of security guarantees,” NATO Secretary General Mark Rutte recently revealed.

To be sure, an American contingent on the ground in postwar Ukraine—working alongside partners that collaborated in other warzones under acronyms such as MFO, IFOR, SFOR, KFOR, and ISAF—would be preferable to what Trump is offering.

After all, American boots on the ground send an unmistakable message to aggressor nations. However, given where Trump was in February, it is important to look at the bright side; rather than taking an ambivalent or even antagonistic position towards Ukraine, Trump appears willing to support America’s closest allies as they secure a postwar peace. The Ukrainian people can then harden their territory against another Russian invasion. There are also two important historical realities.

First, American airpower has a proven track record of making a positive impact on the ground—whether in humanitarian, peacekeeping, deterrent, or combat-support missions. Consider the Berlin Airlift, which sustained a besieged city for 15 months and dealt Stalin a humbling blow. Operations Northern Watch and Southern Watch, which protected Iraqi civilians from Saddam Hussein’s vengeance for 12 years and allowed Iraq’s Kurds to build an all-but-sovereign state is another. Operations Deliberate Force and Allied Force, which, in coordination with partners on the ground, brought Serb paramilitaries to heel in Bosnia, pushed Serb regulars out of Kosovo, and hastened the end of Slobodan Milosevic’s genocidal rule. The toppling of the Taliban after 9/11, which saw the US use airpower as a force-multiplier for indigenous fighters on the ground is but one more example. Finally, Operation Inherent Resolve leveraged airpower to assist ground units in rolling back ISIS in Iraq and Syria.

Of course, no one wants American warplanes directly engaging the Russian military. But it pays to recall that it is already happening on a routine basis—near Alaskan airspace, over the Baltic Sea, across Pacific Ocean, and in the Middle East. Moreover, given recent encounters between American and Russian forces—and American and Russian hardware—it seems unlikely Putin’s high command will want to challenge American airpower along or above a future Ukraine-Russia DMZ.

That brings to light a second set of historical lessons. Neither lingering territorial disputes nor simmering hostilities are dealbreakers when it comes to providing security guarantees to allies and partners in the crosshairs. Consider post–World War II Germany. After a period of disarmament and occupation, the country’s western half was rearmed and invited into NATO as a full member, despite massive Soviet bloc armies ringing West Berlin and despite West Germany facing an overwhelming military disadvantage across a heavily armed border.

In fact, the US did not formally recognize the post–World War II territorial-political settlement in Germany or across Europe until 1975. The people of West Germany never abandoned their hopes for German reunification. Those hopes were not realized until 1990.

Next, consider post–World War II Japan. The Red Army seized Japanese islands at the end of the war. To this day, Tokyo does not recognize Russian control over those islands. Despite this territorial dispute, the United States guaranteed Japan’s security in 1951 and entered into a full-fledged mutual-defense treaty in 1960. That treaty is still in force today.

Last, consider the Korean Peninsula. Despite territorial disagreements; despite the absence of a peace treaty; and despite, or perhaps because of, the threat posed by a massive hostile army north of the 38th Parallel, the US provided open-ended security guarantees to South Korea in the autumn of 1953. Those security guarantees are still in force. The people of South Korea still look forward to unification of the two Koreas under the banner of freedom. South Korea even has a cabinet-level government ministry focused on unification.

Predator

In none of these examples did the US or its allies agree to the permanent ceding of territory. Rather, they recognized the difficulty of liberating occupied territory and they envisioned the future prospect of the return of that territory. That is how Ukraine and its partners should view the imperfect peace that will emerge in the coming months—a peace that will leave some of Ukraine’s territory under Putin’s control.

It is also worth emphasizing that a European-led, US-supported peacekeeping force in Ukraine is necessary given Putin’s policies and plans: Moscow occupies swaths of Georgia, Moldova, and Ukraine; threatens Poland; is conducting a campaign of sabotage operations across NATO’s footprint; has moved nuclear weapons into Belarus; is firing off intermediate-range missiles; and is diverting 35 percent of government spending into its war machine. As French President Emmanuel Macron concluded, Putin is “a predator…at our doorstep.” Putin will not stop until he is stopped. Securing Ukraine—while continuing the build-up of deterrent forces on NATO’s eastern flank—is key to stopping Putin.

Trump’s Path to an Imperfect Peace in Ukraine was originally published on Global Security Review.

Vance addressed the continents’ hostile stance on freedom of opinion. He suggested Europe is becoming the enemy they opposed during the Cold War, and with elections coming, challenged Europeans to step up and take charge of their own defense. Vance also argued that the most urgent issue shared by all nations at the conference was mass migration.

Europe is Not Unified

 Incidentally, in late 2024, Global Security Review (GSR) published an updated independent assessment of European political uncertainties. It shows that JD Vance’s statements made in February 2025 were factual and fully grounded, even if inconvenient.

The governments of France, Germany, and the United Kingdom are fractured and dysfunctional. Another late 2024 GSR independent assessment of an endgame in Ukraine suggested an uncomfortable realpolitik-driven negotiated settlement, even before the Trump administration offered its plan after the Munich Security Conference.

That suggests two observations. First, the complete terms will never be made public but are already known to powerbrokers. Present neutrality of Russian forces in Transnistria and a lack of attacks on Ukrainian leadership suggests some form of agreed limitation of the conflict. Recently both Vance and Secretary of State Marco Rubio remarked on Zelensky’s duplicitousness. Apparently, he would agree to terms in meetings and then lie to the media about them. The ostentatious way Zelensky ended up confronting both President Donald Trump and Vice President Vance in the Oval Office, despite the rather realistic and transactional path to settlement, only reinforces this assessment.

The indignation and moral outrage over the conflict is mostly performative for the media and the public. It gives governments cover to prolong the conflict by providing aid, winning elections, and increasing the size of their bureaucratic apparatus, along with the corrupt mechanisms endemic to Ukraine. What online outrage does not do is enable a negotiated settlement of hostilities.

After the White House debacle, President Macron arranged an emergency meeting. While President Macron again pushed for “strategic autonomy” for Europe, the emergency meeting again showed that other European countries are not getting on the France bandwagon just yet. Together with the UK, France is the most likely to send troops to Ukraine, an idea that both Germany and Poland loathe. Italy is attempting a pragmatic balancing act between Europe and the US. Regrettably, the Baltic and Nordic countries, who are the frontline against Russia and invest the most in their defense, were not represented in a meaningful way.

Second, the claims of America “abandoning” Kyiv are hyperbolic, counterfactual, and premature. This is an ongoing negotiation. The facts are clear. The US provided 0.6 percent of its 2021 GDP to Ukraine and more than $160,000,000,000 in financial assistance and munitions, just about half of all assistance Ukraine has received. This aid, unlike European aid, has no strings attached and no expectation of repayment. The US also secured billions in loans from various banks for the benefit of Ukraine.

Meanwhile, the US is strategically overextended and incapable of matching the more immediate threat (China). The Trump administration understands this. Many Americans know this, too, which is why 72 percent of registered voters want a negotiated settlement. That does not mean President Trump is surrendering to Putin or “abandoning” Europe. Nor does it make him a tool of Putin.

The West is in a bad strategic and operational position. Even after three years of supporting the Ukrainian war effort, weapons production across all North Atlantic Treaty Organization (NATO) member states cannot meet demand, let alone stockpile in case of war in the Pacific. While many speculate that Russia is in bad shape and is showing indicators of economic decline, they are stronger than Ukraine and its immediate neighbors.

For the West there are only two alternatives to a brokered peace: a dramatic escalation led by American conventional forces and resources or continuing to feed the war of attrition. Neither is a good scenario for the Ukrainian people who are dying by the thousands. President Trump understands this fact.

The Future of NATO

How Europe responds to the US remains to be seen. There are deeper fractures within and between the UK, France, and Germany than mainstream observers realize. The only ones significantly expanding their militaries and cooperating with the US are Poland, the Baltic states, and the Nordic countries.

As for the United States’ participation in NATO, it should be scaled back over time and be contingent on shared values with partner nations, especially when it comes to freedom of conscience and speech. Countries like Denmark, who believe Russia will invade Europe in 5 years, should expand their militaries and demonstrate not only commitment to liberal values but self-defense. The United States cannot fund its welfare state and those of Europe. Americans are not that wealthy.

American involvement in NATO should be primarily limited to (1) logistics (air and sea transport to Europe); (2) support in the form of weaponry, materiel, and war support materiel; (3) maintaining freedom of the seas; and 4) developing missile defense systems that can serve American and, when purchased, NATO. The United States also has unmatched space capabilities.

There should be no expectation of American boots on the ground simply because Europe neglected its security obligations for nearly 30 years. While there is still immense value in joint training and cooperation, the US should be seen as a rear guard and a last resort force. American taxpayers should not be the primary funder and provider of military forces and capability for Europe.

It is difficult to expect any long-term peace to be possible so long as NATO serves primarily as an anti-Russia platform funded by the United States. Europeans need to solve their own problems without vilifying the United States for solving American problems first. This means Eastern Europe needs to secure the buy-in of countries like Italy and Spain, who do not feel the Russian threat. As Vice President Vance suggested in Munich, Europeans must reflect on what they are defending and not just what they are against.

Europe is their continent and their home. It is their responsibility and duty to be the primary protectors of their individual nations and European society. Unfortunately, Europe does not appear to be ready to make a unified effort. Nonetheless, the proposal by the newly elected German chancellor, which calls for France and the United Kingdom to share their nuclear deterrent, might be a first concrete step in the right direction.

The US and Europe: A Reality Check was originally published on Global Security Review.

Professional diplomats in the United States and its North Atlantic Treaty Organization (NATO) allies might have wondered if this was an unrehearsed skit from Saturday Night Live.  Only Alec Baldwin playing the role of Trump was missing. Allies do not talk to each other like in front of the media.

It was clear that Trump and Vice President JD Vance expected to have a pleasant conversation in front of the cameras, have a nice private lunch, and then publicly sign a mineral deal with President Zelensky. They did not expect the pushback and demands that came near the end of the conversation. As a famous French diplomat once said, with respect to another diplomatic blunder, it was “worse than a crime. It was a mistake.”

Zelensky ended up being unceremoniously escorted out of the White House without lunch or a deal. The agreement that would allow the United States to mine rare Earth minerals in Ukraine was that it would repay the United States for the more than $160 billion that American taxpayers have invested in Ukraine’s defense. Profits from American mining operations would also help rebuild Ukraine. American businesses operating in Ukraine would also offer de facto security guarantees to Ukraine. Absent such an agreement, it was feared that China may partner with Ukraine to mine these critical minerals.

While President Trump is likely genuine in his desire to see the killing end and Ukraine rebuilt, Ukraine is only a small part of a larger strategic game the United States is playing. The Trump administration believes that Europe is no longer the strategic pivot of international relations. Instead, the focal point of American diplomacy and military preparedness is the Far East, with a rising China as the main adversary standing in the way of American global leadership and international influence. Europe is a secondary theater of operations, and it is time Europeans bare the burden of their own defense.

This view is a tectonic shift in American focus, but understandable. China has ambitions that go well beyond military and political competition with the United States in China’s backyard.

China’s global strategy of multi-domain competition with the US includes all spheres of power and influence. Its tool kit includes explicit challenges to the United States in the development and deployment of nuclear weapons, the military use of space, artificial intelligence development, cyberwar, and economic influence.

China’s ambitious naval expansion may fall short of driving the US Navy from the high seas, but its combined arms approach to anti-access and area denial (A2AD) in East Asia is intended to deter and, if necessary, defeat any power that would oppose China’s mastery of its immediate sphere of influence, including Taiwan.

Nevertheless, recognition of the threat posed by a rising China does not invalidate the strategic significance of events in Europe. America’s commitment to the defense and security of a free Europe is not transactional, it is existential. This is embodied in the NATO alliance.

NATO is the result of symbiotic relationships among democratic states that provide collective security within a context of political freedom. Ironically, this is why JD Vance’s challenge to European allies at the Munich Security Conference was so interesting. Vance noted that the United States and Europe are linked, not only by procedures and financial commitments, but also by shared values, including free speech. He rightly urged the European members of NATO and the European Union to enhance their commitments to free speech that, in his view, are in decline across Europe.

Russia’s aggressive war against Ukraine, with its objective of destroying Ukraine’s armed forces, economy, infrastructure and its viability as a state is clearly grossly immoral. But evil in the world is nothing new, nor is it incumbent on the American taxpayer to fund every effort to eradicate all evil in the world. American efforts to impose liberal democracies where they do not exist has a poor track record of success.

Europe was the cradle of American civilization, but Americans fled Europe because of religious persecution, a lack of economic opportunity, and other reasons that are inconsistent with freedom. Doubtless, Zelensky and other European politicians drive their American partners crazy at times. During the Second World War, Charles de Gaulle drove British Prime Minister Winston Churchill and Supreme Allied Commander General Dwight Eisenhower to distraction.  But the imperious de Gaulle was the symbol of French nationalism for those who opposed Germany and the Vichy regime.

An American abandonment of a free Europe would leave Europe to repeat its past mistakes, which the continent has repeated over and over and over again. Zelensky is far from an ideal partner. However, a Ukraine swallowed by Russia will result in a less stable Europe.

Vladimir Putin clearly sees a free Ukraine as a political and economic threat to Russia.  He denies that Ukraine is a distinct civilization or country. He constantly refers to Ukrainians as neo-Nazis. A negotiated settlement will not change this perspective. Any agreement with Putin must follow President Ronald Reagan’s dictum, trust but verify.

Ironically, one outcome of the war between Russia and Ukraine is the enlargement of NATO with the addition of Finland and Sweden. Thus, NATO added considerable strategic depth and an ability to prevent Russian ships from leaving port in the Baltic Sea. Without the United States, European NATO may waiver. In the end, President Trump’s efforts to push European states to play a larger role in their own security are important, but they should never lead to an American departure from the Alliance.
