Canada

I wouldn’t say the UK was the second most influential—realistically, that spot goes to the US. And I’m not even a big fan of the US right now, but their industrial power, global logistics, and role in both Europe and the Pacific made a massive difference. Without their support, especially through Lend-Lease and D-Day, things could’ve turned out very differently.

Actually, it was the Canadian soldiers that marched through Italy; the Canadian soldiers that marched north to Denmark and protected the American flank; the Canadian landing at Juno beach which not only protected the American flank, but pushed further and faster, greeting the American troops as they finally pushed off of their beachhead; the Canadian top command that developed the more efficient ways of fighting a modern battle, especially the results learned from the essentially Canadian Dieppe raid (which WAS successful, the Canadians got off the beach and made it to the post office for what they went for); the Canadian scientists that worked on the development of the Atomic bomb long before the Manhattan Project, and went on to establish Chalk River; the Canadian merchant marine that kept Britain supplied during the war... the list goes on and on. You do not need to be a tankie, just a good student of Canadian history.

Unfortunately for our Canadian legacy, we do not brag.

While that's largely true, it also oversimplifies the realities of the conflict.

Without American aid the Russians wouldn't have been able to repel the Germans nearly as effective as they did (if at all), and without D-day splitting the war into two fronts, Russian losses on the way to Berlin would've been significantly higher.

That all said, Trump's statement is obviously horseshit and a complete disservice to the rest of all the allied forces.
