Since you refer to economic in your earlier post, Charmion, these were the cost metrics I refer to, not human costs.

I would hardly call the billions spent in the Afghanistan mission "teenie" - which was hardly a peacekeeping nor defensive mission. These resources, IMO, could have been better spent in actual defense, or preparedness to assist in less agressive missions in other parts of the world. While it does not take that many troops to drop bombs (there, in Libya, Iraq, or Syria), the financial costs alone (to the bombed population and to Canadians) are significant.

Considering the lack of transparency (aka Harper) regarding Afganistan, from outside estimates, it is likely that that this mission alone cost Canada between $30 to $40 billion (note the future costs to veterans lingers). Given his way, I suspect Harper would have continued down this path in the middle east, or accelerated it more. Firtunately, Trudeau may inject more sense into the situation.
