Thanks for an article that concedes there are two sides to the story.
Latvia is indeed very much like Ukraine, with a population whose loyalties are divided between the East and West. It does not need outsiders coming in to stir the pot. 
Ukraine was plunged into war because a democratically-elected government that wanted closer ties to Russia was overthrown by a mob. We cheered because it was OUR mob, but Russia was incensed and if you look at it from their point of view they had every right to be. Now Latvia is in the same situation. The citizens are torn between two loyalties but are living together in peace. How does it help the situation for NATO to send in pro-West forces?
Canadian soldiers in Latvia and Ukraine are cannon-fodder. In the event of hostilities Canada, unlike the USA, will be in it from day 1. No chance of neutrality. And on that day, we will all depend on a US president whose loyalties and policies change from minute to minute. 
Absolute insanity.
