3Miscellanea: The War in Iran
- The author, a military history scholar, argues that the US war against Iran represents a strategic blunder based on a failed gamble that the Iranian regime would quickly collapse. Iran is too large and geographically challenging to occupy, while not being strategically vital enough to justify the enormous costs. The administration bet on regime change through targeted strikes, but Iran's institutional structure makes such collapse unlikely. Even if the regime fell, all probable outcomes would leave America in a worse strategic position than before the conflict began.
