Syscom, I have to say that I find your approach to this whole topic truly appalling. The Canadians stepped up to the plate and did their bit - so for you to knock them for sending less troops than the US is worse than mean-spirited, it's crass. Lets not forget the huge industrial effort Canada made too, sending not just bomber crews, but also the bombers for them to fly - by the thousand.
And the war DID start in 1939 - just because the US didn't join then doesn't make it any less of a war. The BoB, the Blitz, the Battle of France, the opening phase of Barbarossa - these were all real and important even if the US wasn't involved And yes, the Ardennes were terrible, but every nation fought protracted and bloody battles in every theater - someone has already mentioned Cassino as an example, and there are more
Your view simply assumes that the US was the only major player in the European War - that is utter rubbish and you and I both know it. Instead of belittling the other Allies, perhaps you might contemplate that for the past 65 years, many of them have stood by you, and continue to do so today - Canada included.
