Iran is bigger than you think
Western debate about military action against Iran often glosses over a basic geographic reality: the country is enormous. At 1.63 million square km, Iran is larger than every country where the United States has deployed ground forces since WW2, often by a wide margin.
In comparison, Afghanistan, the site of America's longest war, covers 653,000 square km, less than half of Iran's landmass. Iraq, invaded in 2003 after months of military build-up, is just 435,000 square km. Vietnam, which consumed 58,000 American lives and years of national anguish, is 331,000 square km, roughly a fifth of Iran's size. Even Somalia, Bosnia and Syria fit comfortably within Iran's borders with room to spare. The smaller interventions are starker still. Kosovo, Kuwait and Lebanon are, in geographic terms, rounding errors beside Iran.
None of this makes conflict impossible. But history suggests that terrain and scale exact a punishing toll on occupying forces. America's post-war interventions have broadly shrunk in size with each successive decade, from the Korean peninsula to the Caribbean island of Grenada. Iran would reverse that trend dramatically.
Geography is not destiny. It is, however, a useful corrective to the assumption that military options come cheaply.
