Did the Vietnam War contribute to the fall of communism why or why not?

The United States was not defeated in the Viet Nam War. When A nation is defeated in war it has to submit formal surrender and is forced to obey any restitution as demanded by the victor. This did not happen in the Viet Nam War. Instead, the US became tired of the war and just left with all of its guns, planes, tanks, choppers, ships and men (at least the ones that were left).

Noone can say for sure what the impact of the US was in Viet Nam, but if communism had been allowed to move in without have to expend so much effort and resources maybe it could have been much worse. Maybe it would not have mattered. Who can say for sure.

As to whether we could have won, well maybe. We restrained our use of force greatly and maybe for the best. Once again who knows...and who really cares? It cannot be proven either way.

It really does seem like a wasted time period in American history. What positive came from it? Not much. It is bizarre that there was a kind of parallel world in the US at the time that was putting people on the moon. One thing is for sure, in the case of things like war it will definitely happen again...and again...and again. It is our nature. Maybe you or your grandkids will oneday be able to tell people you were there when the mushrrom clouds filled the horizon. How special. What can one do, people are a-holes who like to see what is on the inside of each other.
