USA has oceans plenty of AEGIS warships able to shoot down foes ICBM.

USA showed their true intentions of selfdestruction of Middle East in 2011/2012 Hormuz strait tensions, sailing aircraft carriers by pairs in Hormuz strait, and sinking Iranian boats as provocation. Iran didnt bit the bait, but USA showed what they were and what they wanted: Kill own people as provocation to bring chaos to Middle East.
