If you actually believe what you just wrote here, I am ashamed.  Afghanistan, particularly Canada's role there, was a reaction to a key ally being attacked.  Not to mention the 26 Canadians that died due to 9/11.

The wars involved by the countries you mentioned, though including unfortunate collateral damage, was focused on combatants.  The attacks by Muslims (that you have stated are acceptable reactions to being attacked) are focused on killing innocent civilians.

Shame.
