WORLD WAR P!!! Who's leading you?

The military is literally made of random people

Especially during wars! When they draft!

You need a history lesson. USA supplied USSR with a crap ton of stuff. They also benefited from not needing to defend their Eastern flank from the Japanese(they tried but got repulsed by Zhukov), which permitted them to move in a ton of Experienced Divisions to fight the Germans. USSR won on attrition and basically overwhelmed the Germans with sheer numbers. Didn't matter if their equipment was inferior or they had poor Leadership early on due to Stalin's purges in the 1930's(big reason as to why he did the NAP). Attrition and USA material support ultimately won the day.

Can also point to Hitler being an incompetent Military Dictator. Had he annihilated the British Expeditionary Force at Dunkirk, Britain would have folded. Africa would have followed suit with Italy taking over Egypt and the vital Suez Canal. Middle East with its Oil would have permitted them to feed their war machine while also choking off India of support that likely would have led to its demise against the Japanese. With India gone, China probably would have fallen too, leaving USSR in an untenable position by being surrounded on all sides.

USA dropped the bomb to save US troops. My family literally wouldn't be here if it weren't for the bomb because my Grandfather was a POW(Wake island). Shortening the war led to people being alive today that wouldn't be had we not dropped it.

They did, and I'm pretty sure they eventually took charge of Japan temporarily, basically.
