Iran is a threat to peace. Yes, they helped in Iraq, but our folks should have known before they got involved that their being there would mean trouble.
I think our troops should be on a war footing, meaning shoot and ask questions later. Peaceful demonstration is one thing, but once they get violent, I say shoot them down like the dogs they are.
Bush was a pathetic POTUS, and he failed in Afghanistan and Iran both. His tea and crumpets approach to both countries have left us as occupiers. Plain *ss stupid.
