First of all, it DOES make sense... Actually analysts did see a pattern in presidents attacking the Middle East and the upcoming re-election in genera, as Trump is not the first who did an attack on the Middle East which such impeccable timing, and with even an impeachment involved... Yeah, only somebody who willingly wants to look away and be blind for how Trump works, would say that it doesn't make sense! And only fools rule out the possibility that World War III can come from, or from anything for that matter, as that would show that World War I and II didn't teach them anything, and that would include you... Both WWII lead to people utter the same words prior to their beginning you do now, and history taught us how much those words were worth... And speaking of treaties... Hitler had treaties... He just didn't care for them and only saw them for useless piece of paper. I do however not strongly believe this will lead to WWIII, but that Iran takes this for an Act of War committed by the U.S.A. that much is clear, and they could even see this as an open declaration of war. The question I heard experts about that the Iranian government is facing is how the people of Iran will support their government in this matter. Iran is a dictatorship after all and that makes it impossible to hold completely polls in complete independence, and it the people are turning against their government then Iran can forget about their retribution actions.
But even experts say that all scenarios are open now in which WWIII is not the most likely, but not entirely unthinkable worst case scenario, and I said "worried" not strongly believe, those are words you put in, and if you read my post well, you would know that you are saying things based on a comment not properly read.Many wars (if not all of them) began with a "mistake" (either a real mistake or one of the parties lured the enemy into, as you don't wanna be the agressor, do you). When Trump canceled the nuclear deal experts were certain that alone would not cause WWIII. Now I hear them not deeming it likely, but none of them dares to rule it out.
And who stands gain from this? The answer is the same as with all acts of war. The one who commits it thinks he does, but in the end, nobody truly did, and the question arises if there will be a steep price to pay, and if so... Who's gonna pay it?
