I agree- but they could at least bring them to Georgia's southern border. Those G. troops in Iraq won't be useful there now, when their homeland is at war, and if it were to end soon, Georgia will want to have as many as possible close at hand, just in case.The U.S is not going to risk bringing in aircraft over hostile territory, if they do it will be to pick up the U.S advisors and that will be coordinated with Russia and Georgia.
This reminds me of '06 Lebanon bombing by Israel and helicopter - assisted evacuations of Westerners.
Also, even if Russia doesn't have enough regular troops for an all-out war/occupation, she can provide support to Ossetians and Abhazians- with enough arms & training they would keep Georgians in Georgia proper. BTW, the Chehens were only brought under control after the implementation of "devide and conquer" methods!
