Iran or Yemen?
After Iraq, US may need a 10 year campaign to sell a 10 or 20 years (failed) war in Iran. In Yemen, they may get an easy one year "mission accomplished" and then hand over the mess to Saudi Arabia's puppets who may need 10 years to lose again.
I wonder if Trump would win the midterm elections with that, how many dead civilians?
