I forgot to respond to this way back, but The Brits and Muricans wouldn't have been able to launch their D-Day invasion if the Russians hadn't won the Battle of Stalingrad. The Nazi losses at Stalingrad temporarily crippled the Nazi manpower reserves in the Western (French) Theater which kept their resources in Normandy limited and their field armies understrength. I can't begin to imagine how things might have changed had the Soviets not been so determined to hold Stalingrad at all costs.
The soviets carried their team.
They almost solo won the ww2, from 1943 the nazi resources and their military might was already almost depleted.
Joke aside, many serious historians believe that the power balance between the nazis and allied forces was strongly in favor of the nazis from 39 to 41, was somehow equal in the first half of 42, and started to be reversed in the favor of the allied forces from the end of 42.
They believe that the nazis already
theoretically lost the war in 1943, and if they survived two more years it was mainly because they had enough forces in reserve to just slow down their fall. Without the Soviets offensives the allied forces would have been incapable of invading, or if they did they would have lost many more soldiers. (and they already lost a lot)
As for the US involvement in the ww2, people tend to forget that until pearl harbor
they kept a neutral stance and they even
sided with some nazis officers and factories for their own benefits. They even
kept their economical contracts with Germany until the last moment and they were not a real part of the allied forces before pearl harbor, they just economically helped the UK.
If we remove the political thoughts, it's hard to reproach the US higher-ups to do their best for their country's benefit. But when you see how they try to bend history to their advantage, by acting like the nice guys in anything related to WW2, it's kinda disgusting imo.
The two real winners of the WW2 are the
Soviets and the British, and both of them had huge losses. The Soviets rolled down on the eastern front and reached berlin before anyone else and the British always fought and never gave up, even where they stood alone against the Luftwaffe after Paris fell and France lost, they didn't bend.
As a french myself, even tho we like to make jokes about the British, I think that all of us have a profound respect for them and we are grateful for what they did during WW2.
Especially to Churchill, even tho he wasn't perfect he is still the one who granted asylum to
General DeGaulle who is a national hero here. DeGaulle made a radio call from London and regrouped all the remaining dispersed French forces and colonial armies around the world to continue the fight against the nazis and the Vichy regime (occupied french regime).
He made the Resistance in occupied France possible, thanks to that they could
bomb nazis facilities in France and the Resistance made
sabotage,
gave intel to London,
saved the life of many RAF pilots and more importantly
made the D-day possible.
