Recently, it has become fashionable in news commentary and in political pronouncements by members of Congress, among others, to claim that the United States’ conflict with Iran is a defeat and a debacle. Ironically, sources that criticized the Trump administration for Operation Epic Fury starting on February 28, 2026, are now criticizing the President and his advisors for capitulating to Iran on issues like Iran’s nuclear program, shipping in the Strait of Hormuz, and funds for Iranian reconstruction. Other critics argue that the regime in Tehran remains in power and that Iranian proxies, especially Hezbollah in Lebanon, keep attacking Israel, America’s key ally in the Middle East.

There is no question that this war was started without many of the diplomatic and military precursors seen in past conflicts, such as consulting with major allies, the United Nations (UN), and briefing Congressional leaders beyond those required by the War Powers Act. There was also an ambitious list of political and military goals announced from the start, including hopes that Iran’s internal politics could be stirred into rebellion against the Ayatollahs, the Islamic Revolutionary Guard Corps (IRGC), and other parts of the ruling theocracy. Official objectives included destroying Iran’s missile capabilities and its capacity to produce brand new ones; annihilating its navy; ensuring that the world’s number one sponsor of terror can never obtain a nuclear weapon; and ensuring that the Iranian regime cannot continue to arm, fund, and direct terrorist armies outside of its borders. Additionally, Israel sought to weaken or remove Hezbollah in Lebanon, and both the U.S. and Israel intend to further contain other Iranian proxies, such as the Houthis in Yemen and Hamas in Gaza.

The Memorandum of Understanding reached between the United States and Iran in mid-June expedited shipping through the Strait of Hormuz to provide immediate relief for global trade and, inevitably, generated significant revenue for Iran from its oil sales to China and other buyers. U.S. officials pointed to declining domestic gas prices as a positive sign, which also fostered a more optimistic economic outlook ahead of the U.S. midterm elections. President Trump continued to reassure Americans and others that the upcoming sixty-day negotiation period between Washington and Tehran would prevent Iran from developing or obtaining nuclear weapons. The U.S. claimed that Iranian negotiators had agreed to future inspections of Iran’s nuclear enrichment facilities by UN atomic inspection experts, though Washington also emphasized the need to include American inspectors. Some Iranian officials denied agreeing to this inspection requirement, but these denials might have been aimed at appeasing hardliners within Tehran’s postwar regime.

Now comes the harder part. Negotiating the end of a war involves more complexity than most observers may realize. This is true even when the stronger power, in military terms, has the capacity to inflict greater damage on the relatively weaker power. Losing powers, not fully defeated, may still retain bargaining chips. The weaker side can influence the transition from midgame to endgame, making it more or less costly for the stronger power, depending on how willing the stronger power is to negotiate and trade concessions rather than simply enforce a diktat.

Regarding Iran, the first aspect of its ongoing ability to stir trouble lies in its close influence over Hezbollah in Lebanon, Hamas in Gaza, and the Houthis in Yemen. Israel continues to respond strongly to attacks by Hezbollah, and this back-and-forth creates a distracting layer for the ongoing U.S. negotiations with Iran. A second aspect of Iran’s postwar influence is its capacity to strike regional neighbors that support U.S. military bases or wish to maintain friendly relations with the U.S., including the United Arab Emirates, Kuwait, Qatar, and Bahrain. Third, Iran is already suspected of supporting assassination plots against President Trump or planning other anti-American terrorist activities. Fourth, Iran has used its own narratives about the war with the U.S. to portray its regime as a victim of a bullying superpower, a storyline that appeals to many observers who were already critical of U.S. support for Israel’s war against Hamas following the October 7, 2023, massacre by the latter. Fifth, Iran’s proximity to the Strait of Hormuz presents potential opportunities for disruptive actions against merchant ships and U.S. or other naval forces. Lastly, Iran’s ongoing close ties with Russia and China will gradually enhance its postwar military capabilities and economic rebuilding, while also reinforcing the stability of its political regime.

Notwithstanding the preceding cautionary notes against premature American irrational exuberance over Operation Epic Fury, a pessimistic assessment of U.S. military effectiveness, and talk of postwar U.S. political defeat, is unwarranted. Iran’s military capability has been seriously degraded, and major components of its nuclear program are buried under rubble, pushing back the estimated time for weaponization. Several rounds of anti-leadership targeting have scrambled the decision-making process within an already complexified regime structure. It is likely the regime will continue to maintain its powerful grip over the population unless, or until, home-grown opposition becomes much more motivated, better organized, and widespread. Meanwhile, we can assume that U.S. Central Command will maintain vigilant regional overwatch to keep Iran’s mischief within acceptable bounds.

Going forward, the endgame in Iran will test the ability of the United States and Israel to exercise both statesmanship and military power. Politics in the Middle East is as challenging as any. War in the Middle East, from ancient times to today, has been the graveyard of imperial ambitions and the source of frustration for efforts to spread democracy. Reshaping Middle Eastern political alliances for international peace and security requires high-stakes diplomacy, cultural understanding, and a strong dose of diplomatic and strategic realism. In the post–Epic Fury world, we stand on the brink of potentially historic breakthroughs that could lead to lasting regional peace, free from nuclear coercion, or, if they fail, sustain the cycle of theocratically motivated conventional or unconventional warfare.

The United States Did Not Lose the War Against Iran: The Harder Part is Postwar Peacemaking was originally published on Global Security Review.

Amid U.S. involvement in a war against Iran, President Donald J. Trump has decided to double down on previous public expressions of disregard and distrust toward NATO. President Trump has threatened to withdraw the United States from NATO several times since his reelection. His repeated jibes at the alliance have raised concern among European defense experts and government officials. Former U.S. Ambassador to NATO Ivo Daalder recently noted that “It’s hard to see how any European country will now be able and willing to trust the United States to come to its defense.” And French President Macron indicated on April 2nd that, in his view, U.S. President Trump was undermining NATO through his repeated threats to withdraw from the alliance. Raising new fears of American abandonment on the part of European leaders, Trump, in various interviews and social media posts within a few days, said that the United States “will remember” France’s refusal to assist in the war against Iran; that NATO was a “paper tiger”; and that “Putin knows that, too, by the way.”

The most recent Presidential broadsides against NATO reflected Trump’s frustration with European allies who chose not to involve themselves in the war against Iran and/or denied their political and military support for the actions taken under Operation EPIC FURY—an effort that Secretary of War, Hegseth describes as “laser-focused [to] destroy Iranian offensive missiles, destroy Iranian missile production, destroy their navy and other security infrastructure – and they will never have nuclear weapons.” But this hesitancy among European allies should not have surprised U.S. leadership. Neither NATO as an alliance nor individual European governments were consulted before the decision to go to war, nor were they fully informed until the operation was already in progress. Further to the issue of NATO support, Trump’s address to the nation on April 1st simply assumed that the United States would wind up its military operations within several weeks and would turn the problem of unblocking shipping in the Strait of Hormuz over to European countries and others. In addition, Western European governments have strong public support for putting distance between themselves and the war in Iran. Popular majorities in every country oppose the U.S. and Israeli campaign, and European opposition to the war is enhanced by Trump’s personal unpopularity on that side of the Atlantic.

An additional element in the split between Trump and NATO was the Russian interpretation of its implications for the war in Ukraine, and more broadly, for Russia’s national security strategy writ large. Prolonged U.S. commitment to war in the Middle East could deplete the availability of military assets that would otherwise be available to sustain Ukrainian forces in their fight against Russia. The global spike in gas and oil prices was an obvious boon to the Russian economy and, from the standpoint of Ukrainian President Volodymyr Zelensky, an unwelcome distraction for European leaders from the priority of supporting Ukraine. Russia also took advantage of Epic Fury to reinforce its support for Iran by providing targeting information for Iranian missile attacks against Israel and other regional states. Russia and Iran had already been sharing technology and knowledge with respect to drone warfare even prior to the launch of military operations against Tehran.

To some extent, the volatility in the Trump administration’s approach to NATO reflected the President’s frustration at his inability to broker a peace agreement between Ukraine and Russia. Vladimir Putin viewed Russia’s war as existential and refused to acknowledge that there was any distinction between Ukrainian and Russian civilizations, let alone sovereignties. The Ukrainians responded in kind, resisting Russia’s invasion and occupation of Ukrainian territory with creative use of drone technology and edgy defensive strategizing that put at risk a variety of targets in Russian territory, including bomber bases and critical infrastructure. Worse for Putin, his invasion in 2022, preceded by Russia’s annexation of Crimea in 2014, refocused NATO on its primary mission of deterrence and defense in Europe as opposed to “out of the area” operations such as Iraq and Afghanistan. Even the formerly Cold War neutral states, Sweden and Finland, were added to NATO’s membership because of Russia’s attempted coup de main against Kiev that turned into the longest and most destructive war in Europe since World War II. Caught in a trap of his own making, Putin continued to pour troops and material into the battlefields of Donbas and elsewhere in eastern Ukraine to support a more favorable negotiating position, should productive negotiations ever materialize.

Given Trump’s propensity for rearranging the deck chairs on foreign policy via Truth Social memoranda, it is conceivable that he will tone down the anti–NATO rhetoric once he has decided on a strategy for winding down the U.S. military campaign in Iran. The process of deconflicting the Strait of Hormuz will likely involve participation from European nations and other countries. Almost nobody benefits from continued bottlenecks in global shipping of oil and other vital commodities. Regardless of the outcome in Iran, the United States needs NATO, and NATO needs the United States. Without the U.S. as the indispensable leading partner, NATO Europe has insufficient nuclear or conventional deterrence against further Russian aggression. This assertion implies no disregard for the steps that the U.S. European allies have already taken since 2022 to improve the quality of their armed forces and military–industrial complexes. It is instead a recognition that the unique American nuclear deterrent and conventional war-fighting capabilities, supported by European determination to resist further Russian aggression, create a global as well as a regional deterrent for Russia and its partners (The CRINKs – China, Russia, Iran, and North Korea) that benefits not only NATO but also world peace. On the other hand, a divided and internally fractious NATO invites further aggression within and beyond Europe.
