Pretty close. No one expected the war to continue the way it did.
The Vietnam War was the only time that the communists defeated an American supported free nation (South Vietnam).
North Vietnam was controlled by communists.
To counter Vietnamese Communists' use of guerrilla warfare
Chi-Coms = Chinese Communists.
The vietcong strikes convinced President Kennedy to send American military advisers to South Vietnam
Yes, they (the communists) won the war.
To fight communists.
The United States was tempted to help France fight the communists in Vietnam. In the 1950s, the American government sent millions of dollars of assistance to France to help with these efforts.
No
President Gerald Ford pulled the last American Fighting Men out of Vietnam in 1975.
The American COLONIES belonged to Britain; America was the property of Great Britain. North or SOUTH Vietnam had no relationship to the US what so ever; SOUTH Vietnam just "happened" to be the next target of the communists. And America (United States) was an enemy of communism. When communists attacked; America responded (during the cold war).
For the communists, yes.
