If you observe that the last deposed leader (Viktor Yanukovych) was Russian backed, you should point out that the current Ukrainian leader (Petro Poroshenko) is backed by the USA. 

Ukraine is trapped in the middle and Canada shouldn't be supporting either.  Eager for war Harper got us into this but Trudeau and Freeland are keeping us there.  

I wish Ukraine well, but don't see that we should be risking blood and treasure for such a US/Russian game with no clear heroes.
