By mid-June 2025, after years of preparation, the Israelis, in one fell swoop, destroyed half of Iran’s ballistic missile capabilities, destroyed some nuclear facilities, and assassinated Iran’s leading nuclear scientists and the leadership of the Islamic Revolutionary Guard Corps (IRGC). Then on June 23, 2025, a pre-dawn bombing raid ordered by US President Donald Trump took out of commission the hard-to-crack nuclear facilities of Fordow, Natanz, and Esfahan.

Beyond adding to Israel’s capabilities with American B2 bombers loaded with GBU-57 massive ordnance penetrators, bunkers busters, the bombing cemented American leadership in dealing with the Iran problem. A review of joint Israel-US capabilities helps explain how deterrence in the region is returning and what to expect next.

Since the October 7, 2023, massacre of Israelis by Hamas, an Iranian proxy, Israeli intelligence and military units, all backed by superior defense technology, methodically destroyed Iranian capabilities and supporters. Iran’s “Ring of Fire” utterly failed to achieve Iran’s strategic aims.

Israeli and American space-based intelligence, surveillance, and reconnaissance enabled early warning, target verification, and battle damage assessment. Israel relied on a precision-strike doctrine that is supported by systems like the Ofek, AMOS, and Eros-B space assets. Israel maintained surveillance for dominance above Iranian military and nuclear infrastructures. Iran merely linked its space program to the IRGC.

With multi-layer sensor fusion, Israel integrates Eitan unmanned aerial vehicles (UAV), ELW-2090 airborne warning and control systems, and ground-based radars like the EL/M-2080 Green Pine with satellite data into a national and regional situational awareness (SA) web, shaping strikes and missile defense prioritization. Space-derived situational awareness enables real-time assessment of missile launches, UAV swarm attacks, or asymmetric maritime threats by Iran and proxies operating from the Red Sea or Persian Gulf.

Cyber intelligence, signal intelligence (SIGINT), and electronic warfare form another layer. In the conflict, Israel command, control, communications, and computer (C4) systems pit Unit 8200 against IRGC affiliated cyber units.

Israel’s missile shield includes Iron Dome, David’s Sling, and Arrow-2/Arrow-3. They combine to create a web of coverage. Arrow’s high-altitude, long-range interceptors tackle Iranian ballistic missiles such as Fattah, Shahab, and Sejil. Iron Beam laser defense, under development, aims to address low-cost, high-volume threats like UAVs and small rockets.

Israeli capabilities for missile defense, early warning, C4, and interoperability are integrated with US Central Command and the systems of the Gulf States. The US supports Arrow and David’s Sling. Aegis ballistic missile defense and terminal high altitude area defense (THAAD) systems in the region share radar feeds. American space-based infra-red system satellites provide missile-launch detection.

Bahrain hosts the US Navy and supports regional C4ISR, and has growing maritime security ties with Israel. The US expanded its Saudi Arabian basing in Tabuk to feed into the regional missile defense picture. The United Arab Emirates enables THAAD, Patriot (PAC-3), radar integration, and air picture sharing with the US and Israel. Jordan, the United Kingdom, and France also contribute to defensive actions during missile and drone attacks.

Iranian targets and their proxies have nowhere to hide. The US Space Force’s Space Operations Command Mission Delta 4 identifies and tracks threats. It did so during the April 2024 and October 2024 Iranian missile and drone attacks on Israel. Operating 24 hours a day, 365 days a year to share intelligence, Mission Delta 4 ensures no missile launch ever catches America or her allies and partners by surprise.

A space-enabled Israel, integrated with Gulf State operations, eliminated Iranian air defenses, triggered covert operations inside Iran, and launched targeted bombings and assassinations. The American bombing topped these other efforts. Israel, as the military strong horse, irreversibly altered the regional balance of power, possibly ushering in the demise of a threatening Iranian Shia hegemony—an objective shared by Sunni Arab Gulf States.

Regime change was never a stated war aim but was an anticipated consequence if it occurred. It did not. The surviving Shia Islamist leadership and IRGC are now engaged in repression and remain capable of inflicting much suffering on both the region and Iranians.

It is unclear to which extent proxies such as Hezbollah, the Houthis, and Shia militias can still attack Israel and American assets in the region. Military outcomes, though, are not the sole factors defining the Iranian endgame. The Iranian taqiyya-driven regime and its Shia hegemony ideology are down, but not out. Their nefarious ideological influence can persist around the Gulf, as far as Yemen and Africa, and beyond.

Considering the cost of inaction and a failure to reinstate deterrence, eradicating a threat to the homeland, Middle East bases, and Gulf allies means the effort was worth it. If the conflict drags on, the costs will rise. Disruption of maritime traffic and oil markets could bring its predictable cohort of economic disruptions. Terrorism around the globe is déjà vu.

In the words of German Chancellor Friedrich Merz, “Israel is doing the dirty work for all of us.” Depending on the roles the new Syrian leadership and a resurgent Türkiye play, the Iranian endgame may take different forms.

Yes, President Trump decisively played the hand he was dealt. But there are many more moves left in this game. The best moves may be still to come.

Deterring Iran: The Art of No Deal was originally published on Global Security Review.

Iran’s Supreme Leader, Ayatollah Khamenei, recently criticized the US proposal for a nuclear deal, while also expressing his doubts about the success of talks. US Special Envoy for the Middle East Steve Witkoff argued that Iran should not be allowed to possess enrichment capabilities and declared such capabilities a red line. Iran, however, rejected the US demand and stuck to the traditional Iranian narrative that Tehran will continue the enrichment process with or without a deal. The divergent positions of the two sides indicated that the talks were likely to reach a dead end, but this time Iran’s nuclear program appeared to have reached a pivotal moment.

As Iran has gained the tools and necessary understanding of enrichment technology, it was unrealistic to think that Iran would completely terminate its enrichment capabilities without the pressure of a war or regime change. Structural realist Kenneth Waltz claimed that if Iran became a nuclear power, nuclear balance and stability vis-à-vis Israel would result. However, it is worth critically reviewing this argument in the context of the South Caucasus region, particularly Azerbaijan, as this challenges Waltz’s notions.

Offensive Realism

In his 2012 article, “Why Iran Should Get The Bomb,” Waltz argued that trying to dissuade a country from seeking a nuclear weapon via sanctions and isolation does not yield a positive result, as the case of North Korea illustrates. Waltz formulated three scenarios regarding Iran’s nuclear program. In the first scenario, Tehran was compelled to end its nuclear program in the face of heightened international sanctions and diplomacy. In the second scenario, Iran developed a breakthrough capability but stopped short of testing a nuclear weapon. In the third scenario, Iran conducted a nuclear test.

It is worth mentioning that in the two decades since Waltz wrote the article, international sanctions and increased diplomatic pressure failed to achieve a meaningful result. Even with the Joint Comprehensive Plan of Action (JCPOA), Iran’s enrichment continued in exchange for sanctions relief. The second possible prediction that Iran will acquire the capability but not test a nuclear weapon can be applied to the present. US Secretary of State Marco Rubio described Iran as on the “threshold of a nuclear weapon.”

Waltz’s central argument is based on the assumption that Israel’s nuclear edge in the Middle East creates an imbalance and that Iran’s intention is to provide a nuclear balance, thereby creating deterrence between Israel and Iran. However, considering Iran’s regional policies over the past decades and its foreign policy instruments, such as using surrogates and proxy forces to destabilize its neighbors and the entire region, one can argue that the notion of Iran’s possession of nuclear capabilities would create “stability” through a nuclear balance does not stand scrutiny.

The ideological nature of the Iranian regime alongside its expansionist foreign policy challenges Waltz’s view. Iran’s increasing ballistic missile capabilities and drone production is an indication that the Iranian nuclear program will facilitate Iran’s offensive nuclear capabilities.

Waltz also overlooked the domestic dimension and variables, meaning the imperialist tendencies within Iran, as well as variables in perception, such as the worldview of the Supreme Leader and Iranian Revolutionary Guard Corps (IRGC) leaders. Moreover, Waltz’s argument that Iran is striving to ensure its own security by possessing nuclear weapons is questionable in the context of the Russia-Ukraine war, which repeatedly shows that having a nuclear deterrent does not shield a country from attack and loss of territory via conventional means.

While structural realists view the international system as anarchic and see states as striving, at a minimum, to ensure their survival, the offensive realist perspective explains state behavior more accurately. In fact, the anarchic nature of the international system directs states to maximize security, and to do so they maximize relative power. Regardless of specific threats states try to expand power. As security is not guaranteed under the anarchic international system, states maximize power to ensure their security.

As John Mearsheimer argues, states maximise their relative power because having military advantage ensures their security. The notion that Iran possessing nuclear weapons is about ensuring Iranian security and creating a nuclear balance fails to address the offensive nature of Iranian foreign and security policies in the region as well as its expansionist approaches.

An offensive realist perspective explains Iran’s nuclear program strategy accordingly, as Iran’s track record and foreign policy instruments show it takes a hegemonic approach in the region to maximize its influence over neighboring countries and increase its relative power. Waltz viewed Iran’s nuclear strategy vis-à-vis Israel, but a nuclear-armed Iran would have a very different geopolitical role in a region like the South Caucasus, sandwiched between two rogue, imperialist regimes—Iran and Russia.

Considering that Iran and Russia are strategic allies that share common geopolitical views of the West and desire to curtail the Westward-looking foreign policies of the South Caucasus, particularly Azerbaijan, a nuclear-armed Iran will not create a balance but push regional actors towards Russia against their will—particularly considering that membership in the North Atlantic Treaty Organization (NATO) is unlikely.

According to Robert Gilpin, “As the power of a state increases, it seeks to extend its territorial control, its political influence, and/or its domination of the international economy.” Thus, a nuclear-armed Iran would engage in solidifying and maximizing its geopolitical goals and interests in its neighboring countries, creating more instability.

Iran’s Nuclear Programs and the Region

The lessons of Russia’s imperialist war of aggression against Ukraine and Russian official narratives such as the rejection of Ukrainian identity and statehood are proof that Iran’s nuclear program, and potential weaponization of it, pose an existential security risk to Azerbaijan as an independent country and the South Caucasus region, in general. Iranian imperial ambitions, coupled with a grudge against Azerbaijani independence, puts the country’s security at risk.

Azerbaijan’s close ally Turkey, which does not possess nuclear weapons, cannot serve as a counterweight for a nuclear Iran. Iran prefers a weak Azerbaijan on its northern border.

Iran also prefers to use Azerbaijan’s neighbor, Armenia, against Baku. A nuclear Iran might further embolden Armenian revanchist circles to seek a change in the status quo, which could start another war.

A nuclear-armed Iran may also increase its efforts to destabilise Azerbaijan via proxy groups, such as the Huseyniyyun Brigade, as Tehran attempts to curtail Azerbaijan’s independent foreign policy. However, a nuclear deal may still allow Iran to use the lifting of sanctions to increase its political and economic influence in Azerbaijan and the South Caucasus via soft power and proxies.

Thus, a nuclear agreement with the United States and fielding nuclear weapons both pose potential risks. The Iran-Russia 20-year strategic pact, which was signed recently, also points to the fact that both Moscow and Tehran will further cooperate and stand against a Western role in the region. Increasing Iranian-Russian military cooperation is also a point of concern. Both countries are heavily sanctioned internationally, but they do not pose an obstacle to the growing trade and military ties between the two states.

Azerbaijan’s position as a link between the West and Central Asia, bypassing both Russia and Iran, is an irritant in Moscow and Tehran. Iran’s staunch opposition to Armenia-Azerbaijan normalization is evident in its stance against the Zangezur corridor as Tehran does not want to lose leverage in the South Caucasus as Armenia’s close ally. The facilitation of the transfer of Indian weapons to Armenia and the transfer of Russian weapons to Armenia via Iranian soil illustrates the fact that the Iranian regime continues to be a source of destabilization in the region. In short, a nuclear Iran allied with Russia cannot establish a nuclear balance in the South Caucasus region; rather it will increase security risks and pose an existential threat to the independence of Azerbaijan and Georgia.

Contrary to Kenneth Waltz’s argument that a nuclear balance would lead to stability, this analysis suggests it will instead lead to instability—particularly in the South Caucasus. As Russia’s war on Ukraine shows, direct imperialist activities by a nuclear Iran cannot be precluded from the future of a nuclear-armed Iran. In short, a nuclear-armed Iran is bad for the Middle East, the South Caucasus, and the World. It will not bring Kenneth Waltz’s stability.

A Nuclear Iran Would Pose an Existential Threat to the South Caucasus was originally published on Global Security Review.

In 2018, President Donald Trump withdrew from the JCPOA, the nuclear agreement brokered by President Barack Obama in 2015, as it “failed to protect America’s national security interests.” Trump justified his withdrawal by arguing that the agreement, as “a windfall of cash”, did not curbed Iran’s malign activities. Instead, he contended, it provided financial resources that “enriched the Iranian regime and enabled its malign behavior.”

For Iran’s non-Persian national and ethnic groups, the failure of the JCPOA was also due to its disregard for human rights and domestic oppression. Western negotiators prioritized nuclear and missiles restrictions and regional security while sidelining the people’s suffering under an authoritarian regime. The economic relief from the deal landed in the hands of regime elites, particularly the Islamic Revolutionary Guard Corps (IRGC) and their affiliates. Ordinary peoples saw little benefit. Instead, the regime doubled down on its crackdown against marginalized groups, including Kurds, Baloch, and Arabs. With reduced external pressure, Tehran felt emboldened to impose its Persian-Shia ideological hegemony even more aggressively.

Now, with talks of a renewed deal resurfacing, one must ask: will this agreement, like its predecessor, serve only the regime’s interests? Trump’s letter outlined conditions for sanctions relief, including an end to Iran’s nuclear weapons program, cessation of uranium enrichment, ceasing financial support to Hezbollah and halting arms transfers to the Houthis, and dismantling its militias in Iraq. However, these terms, like before, fail to address the human rights abuses within Iran. If a future deal ignores these realities, it will once again be the oppressed groups who pay the price.

The absence of human rights considerations in Western negotiations with Iran is not incidental—it is a consistent pattern. Historically, the West has often prioritized short-term strategic gains over the long-term aspirations of the people in Iran. The result has been a cycle of diplomatic engagements that empower the ruling elite while leaving everyday people in a deepening state of economic hardship and political repression. Sanctions relief, while theoretically aimed at improving the people’s economy, has instead served as a financial injection for the regime’s military-industrial complex, allowing it to tighten its grip on power.

For Iran’s diverse population—comprising Baluchis, Kurds, Armenians, Qashqais, Azeris, Arabs, Turkmens, Gilakis, Tabaris, Talyshis, and religious groups including Jews and Bahais—a nuclear deal that fails to address their plight could be devastating. The regime’s persecution of non-Persian groups has been marked by disproportionate executions of Kurds and Baluchis, arbitrary detentions, and systematic cultural suppression. Economic marginalization has left these groups disproportionately affected by unemployment, poverty, and lack of access to basic services. A deal that does not explicitly condition sanctions relief on improvements in human rights will serve as yet another tool for the government to sustain its policies of repression and forced assimilation. Moreover, the suppression of dissent extends to students, journalists, and activists who have faced severe crackdowns for expressing opposition to the regime’s policies.

This regime operates outside conventional norms, yet Western commentators in mainstream media, instead of acknowledging the ideological and religious motives of Iran’s Shi’ite rulers, continue to search for rational justifications that overlook the regime’s true nature. If the past is any indication, a nuclear deal without guarantees for the people of Iran will reinforce the status quo: economic benefits funneled to regime elites, intensified repression of national and ethnic minorities, and continued expansion of Iran’s regional influence at the expense of its citizens. A more “comprehensive” approach to diplomacy with Iran must incorporate human rights as a core negotiating principle. Strict oversight and accountability measures must be implemented to prevent state-controlled entities, such as the judiciary, from imposing verdicts on the people, and the IRGC from monopolizing financial resources and oppressing dissidents. Furthermore, human rights organizations and genuine opposition figures should have a voice in shaping the terms of any agreement.

Ultimately, the goal of any nuclear deal should also aim to create conditions that empower its people to pursue democratic aspirations. A policy that prioritizes human rights alongside the security of Israel and the US would be strategically effective in fostering long-term stability in the region.

Nuclear Diplomacy or Regime Survival? Rethinking the Iran Deal was originally published on Global Security Review.

This is not a proxy war from the Cold War or the Global War on Terror. The West is in a hot war with Iran, and the United States must act accordingly. American focus on containing the conflict in Israel and Gaza is undermining Israeli deterrence. An anemic campaign of limited attacks against the Houthis is failing to deter Iran in the Red Sea, damaging American credibility and promoting Iranian and Houthi prestige.

By contrast Israel understands it is in an existential fight and has an appropriate strategy.  They are systemically destroying enemy forces and can hold Iran’s high-value targets at risk.  Iran should not doubt that October 7, 2023, put its nuclear program and critical infrastructure on the target list. Israel will deal with the Iranian threat with or without American support.

For Israel, American involvement is always a two-edged sword. American politics, Western pressure, and arbitrary red lines are often liabilities that disadvantage Israeli deterrence.  In fact, Israel began a no-holds barred information campaign, targeting media and anti-Jewish forces in the US and Europe. Some Israeli voices attacked the “River to the Sea” narrative characterizing the “two-state solution” as a de facto Iranian occupation of the Jewish homeland.

Deterrence is a coercive spectrum from positive to punitive. Carrots are not working, which leaves only sticks. Curtis McGiffin argues that provocations by Iran, including more than 160 attacks on American forces since October 7, 2023, combined with anemic policies of appeasement and the bribery of Iran, irreparably damaged deterrence in the region.

McGiffin points to statements by IRGC General Hossein Salami that Iran is not afraid of war with the United States. Why should they? Iran’s conduct of grey zone war for decades, with few repercussions, only encourages further aggression. Finally, McGiffin argues that America must formally declare war if we are going to cross the Rubicon and attack targets inside Iran.

That position is debatable. After the Cold War, conventional military superiority empowered the US to act whenever there was sufficient will, constrained only by the imperative to avoid escalation with another nuclear-armed power.

Game theory can be instructive in this case. It teaches risk aversion (Prospect Theory) is a powerful incentive and a key predictor of behavior. Decision-makers will irrationally forego probable gains to avoid improbable losses. It also shows that in an iterative game, players learn from previous opponent actions. The Mullahs learned from American behavior that the US is irrationally risk-averse when it comes to conflict with Iran.

Diplomacy is insufficient without a credible threat to back it up. The United States is standing in a forest fire asking everyone to put away the matches when it needs the deterrence equivalent of backburning. This requires the President to take a significant step up the escalation ladder to re-establish deterrence. Israel is doing this while the US dithers.

Iran is a cancer that has metastasized to threaten the region and the world. America’s ineffective tit-for-tat strategy only emboldens Iran. However, since the hostage crisis (1979) and the Desert One/Operation Eagle Claw fiasco, there was/is little American appetite to deal effectively with Iran. As a result, Tehran has capitalized on American weakness at every turn.

Presidents Ronald Regan and George W. Bush deterred the nation’s enemies by inflicting unacceptable losses, backed by overwhelming military and economic capacity. Operation El Dorado Canyon missed killing Muammar Gaddafi by minutes. The US Air Force enforced no fly zones over Iraq for a decade to punish and contain Saddam Hussein. After the American removal of Saddam, Gaddafi opted out of the extended axis of evil, voluntarily eliminating his weapons of mass destruction programs and long-range ballistic missiles. Even President Bill Clinton “went downtown” bombing Serbian power plants and Serbian President Slobodan Milosevic’s cronies. Instead, Presidents Barack Obama and Joe Biden bribed Iran and put the United States only twelve days away from an Iranian nuclear weapon.

Iranian instigated attacks in the region can no longer be met with impotence and half measures. Swift decisive American action directly against Iran is now essential. Drone attacks on American forces call for the prompt destruction of Iranian drone production facilities and IRGC command and control nodes inside Iran. Harassment of international shipping and attacks on US naval vessels require the destruction of Iranian naval forces and oil-exporting infrastructure.

Chamberlain was wrong in 1939 and his disciples are wrong today. Iran is an implacable foe, and it must be de-fanged. America must make rational choices based on reality. The Mullahs began their war against the US on November 4, 1979. After 45 years, the only rational strategy is to eliminate Iran as an existential threat.

The immediate elimination of the Iranian nuclear program is a necessity. Anything less is delaying an inevitable conflict with a nuclear-armed enemy determined to kill Americans and incinerate Israel.

The US Is Undermining Deterrence with Iran was originally published on Global Security Review.

In response, Iranian Foreign Minister Javad Zarif wrote a letter to President Hassan Rouhani and Iran’s Supreme National Security Council (SNSC) asking that U.S. Central Command (CENTCOM) be designated as a “terrorist organization” in a reciprocal move, a measure already promised by some Iranian lawmakers. Shortly after that, Iran’s SNSC stated that the U.S. government was a “sponsor of terrorism” and designated CENTCOM and all affiliated forces as “terrorist groups.” Now, a new wave of tensions could spread through the region.

Too big a bite for CENTCOM to chew?

Many have argued that the U.S. is retreating from its role as a world leader and is moving in a more isolationist direction. Others point to a need to reconcentrate U.S. resources in response to the oft-mentioned return to “great power competition.”

China—and Russia, to a lesser extent—are engaged in expansionist agendas as the U.S. has been preoccupied with events in the Middle East. Many believe the time, energy, and money the U.S. has spent for nearly two decades in the region would have been better spent countering the influence of the country’s real revisionist threats.

While the U.S. remains involved in a “forever war” in Afghanistan, and with Iraq still reeling from the aftermath of sectarian conflict and ISIS, the U.S. increasingly seems bent on raising tensions with Iran in light of the recent IRGC designation as a terrorist group.

The U.S. presence and the Shiite Crescent

The Iranian proxies in Iraq, known in general as “حشد الشعبی” or Popular Mobilization Units (PMU), whose commanders such as Hadi Al-Amiri and Abu Mahdi al-Muhandis have close ties to IRGC—and Qasem Soleimani, in particular. In the aftermath of fighting ISIS in Iraq, the PMU is now better organized and equipped.

With the recent designation, these groups, with their close ties to their Shiite Iranian allies, can undoubtedly escalate the level of violence in Iraq. According to The New York Times, the recent move could even push the Iraqi parliamentarians to fuel a proposal limiting the movement and actions of the approximately 5,000 American troops in Iraq.

Hezbollah, based in Lebanon, is arguably the most loyal Iranian proxy group. With approximately 45,000 fighters, having alongside the IRGC in Syria, the Hezbollah militia has proven itself to be a capable force in implementing Tehran’s regional strategy. The PMU and Hezbollah—essentially two foreign branches of the IRGC—will pose challenges for the U.S. forces. While the United States would undoubtedly emerge tactically victorious from any conflict in the Middle East, two questions remain: at what cost, and after how long?
