when usa and uk steal credit

Guess you never heard of the War in the Pacific

Fun fact the soviet union with the exception of tanks almost all of their equipment was American produced and in China the only reason that it wasn't completely taken over was due to the flying tigers an American Air division and France fell in the first thirty minutes but even the freedom fighters used American equipment that was air dropped over france

doubtful

Not really

You're just making stuff up. The US provided steel, some of which could have been made into Soviet tanks. 100 fighter planes can't take the credit for defeating the Japanese when there were 3.5 million Chinese soldiers on the ground also fighting the Japanese.

Never said that they did but the Chinese did not have air superiority and no matter how many troops you have if there's someone in the sky shooting at you and your too far away you wont win
