Does the West bear any guilt over what's happening in Syria?

Syria's largest city has fallen. Aleppo, which has a history stretching back five-thousand years, became the focal point for the armed uprising against Bashar al-Assad. It's now a scene of blood-soaked rubble. A UN official called it wanton slaughter. Should Canadians have done more? What now? 

After years of fighting and months of bombardment, rebel resistance in the city of Aleppo came to a bloody end. Syrian soldiers and their allies not only recaptured eastern Aleppo — they crushed it.

Footage posted on social media was horrifying: neighbourhoods flattened, the dead in the streets, reports of 82 civilians summarily executed — including women and children — and a mass flight of citizens in search of safety. It was an especially bloody turn of events in a brutal war marked by barrel bombs and chemical weapons, a war that's claimed over four hundred thousand lives and displaced millions of people.

Western politicians and diplomats voiced outrage, called emergency debates, and demanded safe evacuation for civilians stranded in eastern Aleppo. But some say that hand-wringing amounts to indifference. Comparing events in Syria this week to atrocities in Rwanda and Yugoslavia, they suggest the West turned a blind eye to suffering in Syria. 

Should we have done more in Syria? What more could be done? Canada's Defence Minister called the events in Syria a "tragedy", but won't commit to any military action in the country. What do you think of that response?  What do you think about the UN's inability to impose itself  on the situation?

Our question today: Does the West bear any guilt for what's happening in Syria?
