President Donald Trump said that Iran's nuclear program was "obliterated" last summer, but he now says the U.S. may have to bomb Iran again over Iran's nuclear ambitions.

All of the above are part of the Trump administration's shifting rationale for pummeling Iran and killing its leader without first seeking the buy-in of Congress and U.S. allies.
