Of course you are right, but it does not start with LBJ....you gotta go back to WW II and the deal that was made with Stalin, then post-WW II end of colonialism in Vietnam, India, etc, then follow what happened in China and the rise of Mao, the Korean conflict, and in the early 50's come to Vietnam where the French have been thrown out by seasoned and tough local fighters tired of the oppression, and our very own Pres. Eisenhower and Sec. of State John Foster Dulles collaborated and did not allow the democratic elections which they had promised to occur in Vietnam, thus perpetuating colonialism, not by the French, but by the US, by the time LBJ got involved the whole thing was one huge mess over there.
