I agree with downsizer and Lonewolf on this one. I sometimes wonder just what Cameron and Hague are hoping will come of this? Sadly I don't think it will be any form of western-leaning multi-cultural, secular society. The FSA aren't the good guys in this, anymore than the Assad regime; it is a civil war and we would be best to stay out.
And yes it too felt sorry for the helicopter crew although probably better to go that way than at the hands of the FSA.
