"Encourages Member States to support efforts to ensure the safety and security of areas of Afghanistan no longer under Taliban control, and in particular to ensure respect for Kabul as the capital for all the Afghan people, and especially to protect civilians, transitional authorities, United Nations and associated personnel, as well as personnel of humanitarian organizations;"
I don't think we need to define success beyond the mandate though. As for poppies, Opium, etc. nowhere does the resolution say we need to transfrom Afghanistan into aperfect utopian busting world economy within the next two days.
If we limit ourselves to the mandate itself, then I think the mission is accomplisheable... "to support efforts to ensure the safety and security of areas of Afghanistan no longer under Taliban control, and in particular to ensure respect for Kabul as the capital for all Afghan people, and especially to protect civilians, transitional authorities, United Nations and associated personnel, as well as personnel of humanitarian organizations."
I think that's handleable. It's not even asking us to try to establish democracy there, or rebuild the nation, or even regain control of Taliban controlled regions. It's only asking to maintain stability where we already have control. I think that's the least we could do... no matter how much it costs Canada in lives and money.
