If Germany won. Than we would be in a more advanced world. I'm part Germany, and my grandpa was a natzi. America screws things up. They set up the harbor attack, so they can make money, by killing poor civilians.
But OP I hope you realize how stupid you sound. Go to Germany and spew some of this nonsense to the locals and see how they respond. Yes, tech would be much more advanced. Military tech anyways. Living would be much scarier. Better tech, but at what cost?
I'm Japanese and I'm glad the yanks won. It allowed me to travel there and experience the pleasures of American women.
