Why US Was in Vietnam

We had a treaty with South Vietnam. Our soldiers were not baby killers or crazy. This was a lie spread by the anti-war movement. A Big Lie. If US had won, South Vietnam would be a democracy today, like South Korea, instead of a Communist dictatorship. If Vietnam a peninsula, we would have won, because no HO chi Minh trail. We were not destined to lose. the mistake was not going into Laos to choke off the Ho chi Minh trail. If we had done that, war over by 68.
