I'm going to be a bit contrarian ...
I have said, before and elsewhere, that, in my opinion, every sailor's, soldier's and air force member's life, limb and sanity are forfeit after (s)he enlist and finishes training. Government's should not, but may misuse and abuse their soldiers for their own, partisan, political purposes. In my opinion, again, that is exactly what Prime Minister Justin Trudeau proposes to do.
For the record, I oppose any and every UN mission in Africa because they are all failures or failing. I am even more opposed to joining any French mission because they are all, 100% in support of France's own, partisan and imperialistic policies that we do not share.
I would not oppose sending a Canadian mission to Africa if I thought it was going in pursuit of our own interests, vital or not, which can be stretched to include helping to bring peace and stability to Africa.
