The U.S. directed the war against South Vietnam. There was a political settlement in 1954. But in the late '50's the United States organized an internal repression in South Vietnam, not using its troops, but using the local apparatus it was constructing. This was a very significant and very effective campaign of violence and terrorism against the Vietminh - which was the communist-led nationalist force that fought the French. And the Vietminh at that time was adhering to the Geneva Accords, hoping that the political settlement would work out in South Vietnam.
