Syria – Which Side are we on and why?

I have pointed out before that both sides in Syria are vile and that is one good reason not to intervene in this conflict. As I write the loathsome Clinton woman is in Turkey for talks which she says are aimed to bring an end to the Assad regime as quickly as possible. Now, prepare for your stomach to churn as you watch this video. The Syrian rebels captured a Post Office. The workers were not soldiers for Assad but just Post Office Workers. But they were working for the state and so had to be punished. By being thrown off the roof of what was a seven or eight storey building. What a pleasant way to die for the heinous offence of sorting letters. Please Mrs Clinton can you explain in just a few sentences why it is morally right to intervene on either side in this conflict? Why is one side better than the other, pray tell?
