I think a major part of getting “beat” is they fought the USSR in the east and simultaneously the USA and UK in the west. I mean the war against Stalin wasn’t going super smoothy. But it went on since 1941 already. And it really went south for the nazis when the USA joined WW2.
I won’t say Finland or Thailand were great powers but Japan had a decent showing so it’s not like they were alone
Though it really only took USSR to beat Germany
The USSR was only in the fight thanks to lend lease and even Stalin admitted as much.

Outside of industry the US didn’t impact much
The Western Front was going to be won without them due to German troop and supply limitations
The US war effort was the Pacific and preventing the USSR from taking all of Germany (Allies made it in time)
