... but, where does he think they will go if his AQ rebel force is able to topple Assad?

I'm sure AQ will destroy them....... In terroristic plots waged against the US and her allies.

You're giving him too much credit.  Thinking through consequences of actions is not his strong suit, as witnessed by his whole "red line" fiasco.

. . . We know where they are.  They're in the area around Tikrit and Baghdad and east, west, south and north somewhat.

Oh, wait, wrong war

That was BEFORE they moved them to Syria

FBHO.  That stupid jug earred bastard wouldnt know chemical weapons if it hit the wookie in her big ass.  

We know that the Muslim Brotherhood operatives know that there are chemical weapons in Syria, and would love nothing more than to acquire them, then transfer them into the hands of jihadi pawns who could then be deployed to strike targets on MB's priority list:

* Tel Aviv?
* Cairo during a mass protest?
* London?

There are so many back stories to this whole topic dating back to Saddam, and his support of jihadis after we neutered his ability to project violence in the region across his borders.

This White House is the last group of amateurs and self-haters that anyone would want playing this game in a post-Saddam Middle East, as various factions act to secure their interests.
