Could Iran be coming to a confrontation soon?
Iran could have a nuke in 16 days?
If that is true, and I have no idea how long it takes from having enough enrisjed uranium to build a bomb to actually doing it, then something is going to be happening soon.
There is no way Isreal lets them have one. If Isreali intelligence believe that Iran has a nuke in a matter of weeks, then Isreal will do something about it. That fact alone will cause the US to act, because if Isreal acts on it, then it's no longer an issue of Iran having a nuke to other Arab countries (many of whom I would suspect don't want Iran to have a nuke either), it is an issue of Jews launching a strike on Arabs.
I will point out that this takes Iran at their word that they have 54,000 centrifuges. Who knows?
