Did richland nixon position the united states to win the cold war? Why or why not?

Possibly. The Cold War wasn't really won or lost, it just ended. Nixon started the process of detente, which eased the tensions between the U.S. and Soviet Unions. That was his major contribution to ending the war. I wouldn't say he positioned the U.S. to win the war, but I would say he started the process of ending it.
