Saying that Fins were Nazi collaborators is true, but it's also oversimplified. Finland helped Germany mainly because, they wanted to reclaim land they lost to USSR after the Winter War 1939-1940 - in which USSR was an aggressor. So yeah they helped Germans, but not because they sympathised with Nazi ideology, but because they wanted to regain part of their Motherland. USSR was no angel! These kind of post only show that Soviet (and now Russian) propaganda is very succesful.
Edit: Stalin with Ribbentrop singning Molotov-Ribbentrop pact (division of Poland)
