Robert Kagan on why he believes U.S. faces likely defeat in Iran

Key Concepts

• Strait Control: The strategic control of the Strait of Hormuz, which serves as a critical chokepoint for global energy supplies.
• Strategic Hegemony: The dominance of the United States in the Gulf region, which Kagan argues is currently collapsing.
• Neoconservative Perspective: A foreign policy stance (associated with Robert Kagan) that historically favors active US interventionism to maintain global order.
• Asymmetric Warfare: The reality that Iran can project power and disrupt shipping despite US air superiority.
• Global Power Shift: The transition of influence away from the US toward regional powers (Iran) and global rivals (China and Russia).

1. The Strategic Crisis in the Gulf

Robert Kagan argues that the United States is facing a likely defeat in its conflict with Iran. The core of this assessment is the Strait of Hormuz. Kagan posits that if Iran maintains control over the Strait, it gains "enormous leverage" over the global economy, potentially exceeding the strategic value of possessing a nuclear weapon. By controlling who enters and exits the Strait and charging tolls, Iran effectively dictates terms to the rest of the world.

2. Limitations of Military Strategy

Kagan critiques the current US military approach, noting that despite 37 days of effective bombing campaigns that targeted Iranian leadership, the regime has made no concessions.

• The "All-or-Nothing" Framework: Kagan asserts that the only way to truly reopen the Strait and neutralize the threat is a full-scale land invasion to remove the Iranian regime.
• The Credibility Gap: He argues that the Iranian leadership does not believe the US has the political will to launch a ground invasion, nor does the US public support such an escalation.
• Technical Reality: Even with air superiority, the US cannot protect every individual ship from Iranian fire, rendering current military posturing ineffective.

3. Diplomatic Stagnation and Iranian Defiance

Kagan characterizes the recent Iranian response to US negotiation proposals as a "slap in the face." Instead of capitulating, Iran has demanded:

• Payment of war reparations.
• The lifting of all sanctions.
• Formal recognition of their control over the Strait. Kagan observes that the US currently appears more fearful of restarting the war than Iran, which has emboldened the Iranian regime.

4. Global Implications and the Erosion of Alliances

Kagan links the Gulf conflict to a broader decline in American global standing, driven by the Trump administration’s foreign policy:

• Alliance Breakdown: He argues that the US has "effectively destroyed" the NATO alliance and is alienating allies in East Asia (Japan and South Korea).
• Energy Dependency: Because Japan and South Korea are heavily dependent on Gulf energy, the US failure to secure the Strait forces these nations to seek new security arrangements, further isolating the US.
• Rise of Rivals: The primary beneficiaries of this power vacuum are China and Russia, who are filling the void left by the retreating US influence.

5. Notable Quotes

• "This conflict has revealed an America that is unreliable and incapable of finishing what it started; defeat for the United States therefore is not only possible but likely."
• "The nation that is more afraid of starting the war up again is the United States, not Iran."
• "The United States is now demonstrated not only that it cannot [enforce peace], but that it is not, it can't be really trusted to make sound strategic judgments."

Synthesis and Conclusion

The main takeaway from Kagan’s analysis is that the US is trapped in a strategic "no-win" scenario. Because the US is unwilling to commit to the only viable military solution (a full-scale land invasion) and lacks the diplomatic leverage to force concessions, it is presiding over a shift in the regional balance of power. The conflict is not merely a local dispute but a catalyst for the decline of American hegemony, signaling to global allies and rivals alike that the US is no longer a reliable guarantor of international stability. Kagan concludes that Iran is poised to emerge from this conflict stronger, while the US faces a permanent diminution of its global influence.
