How unfair to our troops. They are supposed to be used to defend Canada. They are candidates for PTSD, especially when they return to Canada, realizing the hopeless and immoral mission they are on. Yes, hopeless and immoral whatever they are doing in that part of the world. 

Certainly we should have learned from our own experience in Afghanistan  without having to think about US experience in Vietnam, Afghanistan and Iraq. Madness utter madness.
