As you know from having studied history, just about the oldest trick that politicians use to rally people around them is the trick of going to war -- especially if they can make it look like the war was the other guy's fault.
With that in mind...
Is Trump trying to provoke Iran into attacking us so he can get us into a war that will rally enough voters to his side in time for him to get reelected?
If so, (1) why do you think so, and (2) why do you think his method of getting us into a war will help him get reelected, as opposed to help him get thrown out of office? Basically, why do you think enough American's to reelect Trump are dumb enough to fall for the oldest trick in the book of politics?
If not, (1) why do you put it past Trump to intentionally provoke Iran into attacking us, and (2) why do you think he has picked this particular minute in history to provoke Iran?
