I have read various takes on the issue and will freely admit I don’t know enough on the topic to make an informed judgment. Some seemingly informed authorities say that the Domino Effect was a myth and that had there been no war* in Vietnam then not only would no more nations have been taken over by Communists than were anyway, but that Cambodia likely would not have succombed to Pol Pot. Other writers say that it was directly because of our involvement in Vietnam that other nations did not fall and indirectly the reason the USSR ultimately collapsed of complete exhaustion in the late 1980s. Still other sources I’ve read speculate that without Vietnam there would possibly have been a war between the USSR and China.
I defer to the judgment of those better read than myself (I’ve read Karnow’s book, Fire in the Lake, a couple of bios of Ho Chi Minh and many articles and websites but nothing truly definitive). What do you think would have been the result had U.S. involvement in Vietnam had decreased or ended in the early 1960s?
*Note: I’m well aware it was not a war officially, though for the purposes of this thread feel free to use war, conflict and other terms interchangeably (unless of course you’re discussing it not being a war).
