I wouldn't be surprised, at all, if it was Rump who was being manipulated by Pompeo & 'Stache. They're the ones who really and truly want to go to war with Iran. I think Rump is being wagged by the Pompeo dog. What Rump wants is entirely irrelevant, good or bad. They either want war with Venezuela or Iran. Putin apparently has let the regime know to keep their hands off the South Amer. country. So, Iran it is.
Pompeo & 'Stache are the ones driving the car off the cliff.
