[Courage the Cowardly Dog]

I hardly think any of those options would sedate the country short of genocide.

The main reason we have fighters coming in is Syria and Iran believe we ARE an occupying force like the crusades and that we will not leave EVER.

Our only hope of ceasing that long enough for the government to deal with it's own threats and not just outsiders who want to knock down them and americans is an international peacekeeping force that goes on the clear contingency that they supply enough troops the american "invaders" can leave and that causes the insurgents to leave and the government can focus on an easily winnable civil war because it would have international backing and NO international fighters from alqaeda flocking in over the borders.

Oh and a border fence wouldn't hurt either once (if) everything settles down.
