I hate to crap on your parade but if we're gonna talk about countries whose contributions to WWII are ignored, look first and foremost at what Finland did. They held off a Soviet force of 1.5 million men for a year, without any outside aid and using nothing more advanced than rifles and molotov cocktails, with the Finnish army being only a quarter million strong. Granted, this was right after Stalin purged every competent military mind from the Red Army and put his troops under the command of politicians and Party butt-kissers, but I still say it's pretty damn impressive. The Winter War, as it was called, was one of the main events that encouraged Hitler to invade Russia, as he saw how poorly the Soviets fared against a seeming backwater with a tiny military.
So, really, you could say the Finns are the reason Hitler lost:P
