> We beat the nazis together

If you by "we" mean Britain, the United States, and Russia. And by "we" mean the people living 2 generations earlier, then I agree with your statement.

As a side note, people who were 18 in 1940, would be 103 today. So most people who fought in the second world war have unfortunately passed away.

I personally would never say "We beat the nazis together". The only thing I did was benefit from the war that generations before me have won.
