The Iran war, which started without warning, has left allies, markets, and lawmakers guessing about its end.

The U.S. and Israel have also discussed sending special forces into Iran to physically secure or destroy its nuclear stockpile. However, this mission would require boots on the ground in a country where the nuclear threat is still active.
