"The destabilization of that region was the fault of France. They took control of the whole area under the name French Indo-China. Froggie ran when things got rough and the good ol' US of A got stuck cleaning up the mess."

Destabilisation of the region was caused by the Japanese invasion during the Second World War - That was Ho Chi Minh, Giap & Co started fighting. Vietnam was "liberated" by the British at the end of hostilities, then the French returned. Ho Chi Minh decided to continue the struggle and the French came very close to defeating him. But close was and never is good enough and Dien Bin Phu put paid to the French in South East Asia. As with Korea the UN mandated that the country be split North and South, with Ho Chi Minh safely ensconced in the North the United States of America was handed the mandate to look after the South, in exactly the same way that Palestine and Iraq was handed to the British by the League of Nations.
