Almost every youtube commenter argue who was the best in ww2. The some British people usually argue that they were able to destroy the German Airforce in the Battle of Britain which was a game changer. Anyone who thinks that every and anything that is soviet is supreme argues that Russia overwhelmed the German's single handedly and crushed Japan at the last minute. Most North Americans(US and Canada) argue that they won and that Britain would be lost if they had not intervened.
In truth the US had the supplies and reinforcements to make everything happen, the Russians had the numbers, the British held out, the Canadians fought hard, Poland lasted longer than France and fought the Russians and Germans with an outnumbered army, Norway stopped Germany's heavy water production, and France surrendered a bitched to the bitter end(no cares about the Free French Army).
