Yes, the US has left a power vacuum in Iraq, there really is no country of Iraq anymore, the governenment only controls some larger cities. Same goes for Afghanistan, it's no better than it was in 2001.
I'm curious to discuss some opinions on what exactly the US and the west should/could do, if anything, in the middle east.
So if you were in a position of power, what would you suggest?
"Nuke them all!!" Isn't an acceptable answer.
