Take a WWII mythbusting tour, equally distributed in east and west: https://medium.com/exploring-history/wwii-mythologies-east-and-west-ab1b82774b1d
What diverted the Luftwaffe from the eastern front? Anglo-American targets flying over Germany.
The Red Army rode in Studebakers and American jeeps and on trains powered by American locomotives and on American railroad ties. That's why Stalin toasted American war production in Tehran in November 1943. No LendLease and the USSR loses. No USA, and the Japanese army defeats the Japanese navy and Japan goes north into the Soviet Far East and Stalin doesn't have 400000 fresh troops for the December 5, 1941 counter-offensive in front of Moscow. The Soviets were saved by the American threat to Japan as well as the timely arrival of British tanks and Spitfires in September 1941. Ask Richard Sorge, the Soviet spy in the German embassy in Tokyo (watch the movie Spy Sorge on youtube).
After the popular outcry over 7000 dead marines in the pointless battle of Iwo Jima Eisenhower and Truman knew sending US troops into Berlin was politically toxic. But Stalin didn't have to worry about Soviet citizens voting him out over 300000 more dead soldiers.
At the April 25 Soviet-AmericanTorgau meetup on the Elbe a Soviet commander asked his US counterpart what took him so long. The American said German minefields slowed their advance. The Soviet officer said, "well, just use penal battalions to clear them", not knowing that the US army had no such units.
Mythologized history built on narcissistic nationalism and martyrology are borderless equal opportunity idiocies.
