Well, consider this.
Trump abandoned half of his base to do this strike, do you think he will just back down? Or will he do it again if Iran does not submit? Make US guess will only invite a second strike, they will keep bombing it and say "the facilities is now destroyed" instead of just letting Iran to get the bomb.
Now you need to ask yourself this, can Iran get the bomb with the US and Israel on their back? If your answer is yes, then sure, they should just leave the US guessing, if not, then well.......
