As tensions escalate between the U.S. and Iran, experts warn that a military strike targeting Iranian leadership may not lead to a clear-cut outcome. While the Trump administration seeks to avoid another Iraq-style occupation, analysts foresee potential scenarios ranging from a democratic transition to state collapse and civil war in the aftermath of a successful decapitation strike against the Iranian regime.

Why it matters

The U.S. is grappling with how to decisively end its long-running conflict with Iran, but experts caution that a bombing campaign alone is unlikely to produce a stable, favorable outcome. The aftermath of regime change in Iran could have far-reaching implications for regional stability and U.S. influence in the Middle East.

The details

The U.S. has been building up military forces in the Gulf region, including aircraft carriers and support equipment, but has not shown signs of planning for a large-scale ground invasion of Iran. Instead, the strategy appears focused on targeted strikes against Iranian leadership and the regime's repressive apparatus, similar to past actions against figures like Qassem Soleimani and Hassan Nasrallah. However, Iran has fortified its positions in anticipation and is unlikely to be caught off guard again. Experts warn that even a successful decapitation strike may not lead to a clear-cut outcome, with potential scenarios ranging from a fragile democratic transition to state collapse and civil war. The U.S. seems to lack a coherent plan for the day after regime change in Iran.

  • In June 2025, Israel conducted a successful decapitation strike against senior Iranian officials.
  • In January 2026, the U.S. captured Venezuelan President Nicolás Maduro.
  • In 2020, the U.S. killed Islamic Revolutionary Guard Corps commander Qassem Soleimani.

What they’re saying

“If it happens, it won't include an occupation of the country.”

— Donald Trump, U.S. President (Foreign Policy)

“Tehran remembers well how the United States used scheduled negotiations as a smokescreen to entice it to lower its guard ahead of a surprise attack last June, and it is unlikely to fall for the same ruse again.”

— Marc Lynch, Professor of Political Science and International Affairs, George Washington University (Foreign Policy)

What’s next

The U.S. is expected to continue building up military forces in the Gulf region, while Iran remains on high alert for potential strikes targeting its leadership. Experts will closely monitor the situation for any signs of impending military action or indications of how the U.S. plans to handle the aftermath of potential regime change in Iran.

The takeaway

The Trump administration's desire to avoid another Iraq-style occupation in Iran raises questions about its long-term strategy for the region. Experts warn that a military strike alone is unlikely to produce a stable, favorable outcome, and the U.S. appears to lack a coherent plan for managing the messy aftermath of regime change in Iran.
