So the US should double down on the stupid moves that got us into this no-win war in the first place? Bush removed the anti-Iranian tyrant and replaced him with a pro-Iranian tyrant. The two sects are never going to be at peace, and no matter what, the US has no interests there. Get all Americans out of Iraq. It is a quagmire with no good ending.
You being scared does not constitute a reason to not protect our embassies and the people in them.
>Get all Americans out of Iraq
Cool. But they are there right now, and until they are not, they are not going to be left to attack like the ones in Libya.
