InterRegional for Strategic Analysis

InterRegional for Strategic Analysis hosted a panel discussion titled "Shifts in U.S. Decision-Making Toward Iran After the War," featuring Alex Vatanka, Senior Fellow at the Middle East Institute in Washington, as the keynote speaker. Vatanka examined changes in how the U.S. approaches Iran, highlighting that the U.S. has moved away from regime change toward risk management and strategic containment. He explored the implications of recent developments for regional balances of power through several key themes.Implications of the War1. The Strait of Hormuz as Iran’s Main Source of Leverage: Vatanka argued that the Strait of Hormuz has become Iran’s primary source of leverage since its nuclear program has become a less effective bargaining tool with the United States. In the past, Tehran used higher levels of uranium enrichment to exert pressure during negotiations. However, after much of its nuclear infrastructure was destroyed, the threat of disrupting maritime traffic and energy flows through the Strait has now become its most influential tool. The speaker also noted that the crisis exposed a lack of preparedness among U.S. policymakers for this scenario, despite long-standing assessments by U.S. military analysts that the Strait of Hormuz would likely be a central theater in any confrontation with Iran.2. Military Superiority Does Not Guarantee Strategic Success: The speaker stressed that the recent war has demonstrated that military superiority by itself is insufficient to secure strategic success. Maintaining the continuity of economic activity, infrastructure, and essential services is also integral to deterrence. Protecting power plants, desalination facilities, and other critical infrastructure, as well as reducing vulnerabilities and strengthening resilience against disruptions will be essential in any future conflicts.3. Warfare Across Multiple Domains: Vatanka noted that modern warfare extends beyond conventional military confrontation to include cyberspace, maritime security, missile defense, energy security, artificial intelligence, and critical infrastructure protection. He pointed out that the U.S. has employed offensive cyber capabilities against Iranian military facilities, while maritime mines, freedom of navigation, and energy security emerged as independent arenas of competition. The extensive use of artificial intelligence in target identification and strike execution has accelerated military operations and made the protection of civilian infrastructure an integral component of modern warfare.4. The Declining Effectiveness of Traditional Deterrence: According to the speaker, the war has challenged a long-standing U.S. assumption that economic sanctions and overwhelming military superiority would be sufficient to deter Iran. Following Washington’s large-scale strikes and economic pressure, Tehran responded differently than in previous confrontations, adopting a more assertive strategy centered on direct retaliation.A Changing Approach1. Shifting U.S. Priorities Toward Iran: The recent escalation with Tehran has reshaped Washington’s approach to several issues, including deterrence, the use of military force, diplomacy, the role of regional allies, and economic security. Vatanka emphasized that U.S. policymakers had not primarily viewed Iran through the lens of economic security, whereas economic considerations have now become central to discussions of Iran policy. Iran is no longer viewed solely through a security or military lens, but also through its implications for regional and global economic stability, supply chains, and energy markets.2. From Regime Change to Containment: Vatanka argued that the U.S. has emerged from the war less focused on regime change in Iran and more concerned with managing risks associated with Iran’s nuclear program, regional activities, and the security of navigation through the Strait of Hormuz. He noted that although President Donald Trump spoke about regime change during the early days of the conflict, that objective no longer appears to be among Washington’s priorities. Rather than attempting to reshape Iran, the U.S. administration is increasingly focused on preventing escalation and preserving stability.3. Influencing Iran’s Internal Trajectory: Vatanka suggested that the absence of Ali Khamenei after nearly 37 years in power has created a pivotal moment in Iran’s domestic politics. He argued that this period, which could extend up to three to five years, will be critical in determining whether Iran moves toward greater rigidity or increased flexibility. Vatanka also observed that Khamenei’s son would require years to consolidate authority, creating a potential window for influencing Iran’s internal trajectory.4. A More Agile Military Footprint: The speaker argued that advances in technology and rapid deployment capabilities may push Washington toward a military posture that relies on a lighter and more agile presence rather than large, fixed bases. Under this model, the U.S. would retain the ability to intervene quickly through naval and air assets deployed across the region.Growing Divisions Within the U.S.1. Rising Public Opposition to the War: Vatanka noted that the war against Iran has never enjoyed broad public support in the United States. Many Americans view the conflict as lacking clear objectives that would justify its costs and sacrifices. While the public generally supports the armed forces, it is increasingly reluctant to see U.S. troops involved in wars that offer no obvious benefits, particularly amid persistent economic pressures, inflation, and rising living costs.2. Increased Political Pressure on the Trump Administration: The speaker argued that the continuation of the conflict has increasing political costs for President Donald Trump. A growing number of Democratic lawmakers have adopted more outspoken opposition to the war and called for greater congressional oversight of White House actions. Congress has also witnessed repeated efforts to require the administration to obtain legislative approval for continued military operations, even though the White House maintained that the war had officially ended. This has produced an ongoing constitutional and political debate over the scope of presidential authority to use military force.3. Growing Domestic Opposition to Foreign Intervention: Vatanka emphasized that opposition to the war in the U.S. has not been confined to Democrats. This opposition has increasingly included segments of the Republican Party, particularly those who believe the U.S. should avoid prolonged military interventions to reshape political systems abroad.4. Mounting Cost of the War for Ordinary Americans: Vatanka argued that the U.S. debate over the conflict in Iran is no longer focused solely on questions of constitutional authority or the legality of military action. Increasingly, it centers on the war’s direct impact on everyday life in the U.S.. The conflict has contributed to inflationary pressures, rising energy prices, higher transportation and travel costs, and billions of dollars in military expenditures that could otherwise be directed toward domestic priorities. As a result, many Americans have come to view the confrontation with Iran as having tangibly negative consequences for their daily lives.The Role of Regional Allies1. Gulf Perspectives Shape U.S. Calculations: The speaker noted that the war has prompted U.S. policymakers to pay closer attention to Gulf states’ assessments of developments involving Iran, given that any military escalation would have direct consequences for regional security and stability. Iran’s attacks against countries in the region have reinforced Washington’s awareness of Gulf concerns over maritime security and critical infrastructure and the need to factor this into policy decisions. As a result, U.S. discussions increasingly focus on addressing the concerns of regional allies and considering how best to respond to their strategic and security priorities.2. Stability and Protection Remain as Gulf Priorities: Vatanka observed that the prevailing view in Washington is that Gulf states are not interested in expanding the conflict and instead favor diplomatic approaches to managing tensions between the U.S. and Iran. While Gulf countries support policies of deterrence, containment, and defense, they remain wary of prolonged wars and sustained escalation. Their priorities center on preserving regional stability and advancing economic and development projects, which depend on a secure environment capable of attracting investment and supporting long-term economic transformation.3. Gulf Security is Crucial to Economic Stability: The speaker emphasized that the conflict underscored the close relationship between security and economic stability in the Gulf. Any disruption to security, maritime navigation, or critical infrastructure has a direct impact on economic activity. This realization has led to a heightened emphasis on safeguarding regional stability and preventing further escalation, given the potentially far-reaching economic consequences.4. Expanding Reliance on Collective Gulf Security: Vatanka argued that the U.S. has a positive view of efforts to strengthen military coordination among Gulf states, and believes that a more integrated regional security architecture will enhance the region’s ability to address Iranian threats. In this context, he referenced earlier initiatives aimed at promoting Gulf military cooperation and the strategic advantages such cooperation offers both Washington and its regional partners.ConclusionThe panel discussion suggested that the war has reshaped the objectives guiding U.S. policy. Managing risk, preventing escalation, safeguarding the economic interests of regional partners, and protecting critical maritime routes now appear to take precedence over ambitions of regime change or the pursuit of a decisive military victory. At the same time, recent developments indicate that the future of U.S.-Iran relations will increasingly be shaped by domestic dynamics in both countries, alongside regional developments and the evolving role of Gulf actors.
