How does China's role in the Vietnam war in anyway illustrate
China's threat to SEA? Vietnam war and Korean war were clashes of
ideologies that divided the world after WW2. Vietnam, Korea, AND
China were divided into two and war of unification ensued, with the
backing of their respective camps. Why should China be singled out
as being a threat to SEA in the war of unification of
Vietnam?
It was american's domino theory that suggested that SEA would fall
once vietnam falls. And even if that were true, SEA would fall
under communism, not Chinese! Now Vietnam defeated the american, is
Vietnam under Chinese rule now?
Did you read why China invaded Vietnam? after the defeat of the
american, vietnamese were expanding westward by attacking the khmer
inside Cambodia, it was then Deng Xiao Peng decided to teach
Vietnam a lesson by invading into Vietnam. they pulled out later,
nobody won, nobody lost. How could we view that incident as China's
threat to vietnam?
