WHy didnt the united states do more to prevent the tyranny of communism during the cold war?

the united states was the only country after ww2 to have nuclear weapons so why didnt they nuke all of china and soviet union to put an end to those communists pigs once and for all?

We were loosely allied with the Soviet Union and China during the Second World War. And after the war, we were much more concerned with the return of Fascism than Communism. The Soviet Union wasn’t a big deal until they learned how to build nuclear weapons from scientists at Los Alamos National Laboratories in New Mexico. The US didn’t know the Soviets built a nuclear weapon until they tested one in 1949.

Don’t forget that the Soviet Union doesn’t exist anymore. And China is our friend now. They provide us with cheap consumer goods. And they’ve loaned us almost a billion dollars. The only thing they don’t sell to us is oil. The American lifestyle would not be possible without Chinese worker doing 12 hours a day, 6 days a week for $125 a month.
