This is completely foolish. Canada has been training Ukrainian soldiers and supplying military equipment to them. Now some suggest we should be "neutral" peacekeepers along a conflicted border. The Russian-backed separatists will not take kindly to Canadians on their "border", nor could they be blamed for such an attitude.  Moreover, there is no peace to keep, no Security Council mandate, and Moscow has its own--very different--plan. Hell, it'd be safer to send Canadians to Mali.
