“Had his fighter jet had another 1-2 years of competitive warfare...”
Except all of that stuff needed fuel - which Germany was running out of due to our bombing of their facilities, and them having no access to natural resources.
I recall my history teacher saying how they used mules to move the jets around on the ground to save fuel!
My uncle was in the underground in Norway. My dad asked him once about it and he said “The Nazi’s will always be around, and I will never tell anyone, for fear of my children and grandchildren.” Of course hearing this as a kid I always imagined him being the one to blow up the heavy-water plant!
BUT DUDE….without the eastern front, they wouldn’t have been running out of fuel.
You cannot cannot cannot analyze any one factor in a vacuum. Without the Russian front, absolutely no fact about the rest of the war would remain a fact. IT WOULD CHANGE EVERY SINGLE THING about the war, period.
