They're going to need US trainers, US Intel, US logistics, and the US assistance with rebuilding Iraq. Someone will end up making a lot of money putting it back together. There is no way to know if they'll accept our goodwill. As for Syria, if Assad ends up with it, then Russia can pay that bill. I know a lot of the posters here want Putin to have an empire, warm water ports, a flank on NATO, etc. He'll have it thanks to Obama's failures.
What I see is that Iran is running free all over Iraq and enjoying their mutual shiite religion with the 60 percent of Iraq which is shiite and in power. U.S. spending the money and Iran getting the benefits doesn’t look to promising. I wonder what the Israeli public position is on this situation?
Of course they wouldn’t mind U.S. paying for it either.
