There was a study showing almost every revolution happened not because of ideology but over the price of bread.
His name was Marx. ;)
Yeah. We'll see. Under what conditions will you consider yourself right or wrong? My prediction is after killing a few more heads of state, disabling some more striking capability that they'll back off under pressure from the Arab states. Trump will declare it as a victory regardless of what happens and everyone will forget about it. Iran will eventually rebuild itself as it just did, but this time it will take longer (Trump even said that himself, contradicting himself earlier).
