The Soviets won the war in the sense that it was their entry into the war on the allied side (not that of Britain or the US, whatever English-language movies might want us to believe) that was the most decisive factor in the outcome of the war. The idea that we could have won without them is laughable. The Americans didn’t even have enough troops in Asia at the end of the war to occupy the territory that the Japanese had held. The Russians getting to Korea first stored up trouble that we’re still dealing with now.
We weren’t white knights swooping in and saving Europe. We signed away Czechoslovakian land to the Germans and allowed them to keep it despite it not being ours to give away. Telling a Czech that we bailed them out during World War Two is unbelievably offensive.
Strongly disagree-
The US operations in Asia were winding up post-Hiroshima and post-Nagasaki. The Japanese had surrendered unconditionally following the virtually total destruction of two of their cities in 2 single bombing runs.
This lead to the unleashing of the US war machine on the western front. This is the single greatest factor in the west's favour in WW2.
The soviets were helpless in front of the German onslaught. The Germans came within a hair's breadth of seizing Moscow and the Russian oil fields. It was the Russian winter that slowed and eventually halted their advance, not the Russian war machine. Routinely Russian soldiers were sent to the front line without weapons. The implication was that by carrying ammunition only they could retrieve weapons from fallen soldiers. The Russian army was decimated by stalin's purges before ww2 began.
The US on the other hand started with a standing army of ~80,000, and around 120 aircraft. By the end of WW2 their standing army was in the region of 10,000,000, and their Air Force was in the region of 120,000 aircraft, with the manufacturing capacity to produce thousands of planes per day. US industry was unmatched by any other great power in WW2.
Well before Hiroshima and Nagasaki the US were winning the war in the Pacific. They were fire-storming Tokyo daily and were advancing rapidly. This is part of the reason that people today debate about the necessity of the atomic bombs- the argument being that the US were poised for Victory anyway, so that they were unnecessary horrors.
Once the US forces were set against the western front fire storming of Berlin began, and the invasion of Normandy was planned. In response the Germans had to move massive resources to the western front to counter this. This lead to the opportunity for the Russians to begin to push back.
The fact that the Russians beat the US to berlin is the result of a concerted effort to do so. Their efforts to push back are belied by the fact that despite the German advance halting in 1941, they only managed to put the German army into a retreat in September of 1944, some 3 months after the allied landing at Normandy.
The British were the most significant resistance to German aggression in the west given that Spain was neutral and the French fell right at the beginning to the German blitzkrieg. It was however the US presence in the west that turned the tide of the war. US military might was eventually matched in ground troops by other countries, but in terms of naval and air power, the US was (and still is today, really) un-matched in its capacity to control the zones of war through unparalleled air and sea power.
