The Diem regime was supported by the US and didn’t hold elections, going against the Geneva Accords. He cracked down on communists in the south causing them to form a group called the Vietcong.

About 180,000 U.S. soldiers were in Vietnam by the end of 1965. Almost 400,000 were there by the end of 1966 and more than 500,000 by 1968.
During this time, American planes dropped more bombs on North Vietnam than they dropped on the Axis powers during World War II.
The United States began a bombing campaign called Operation Rolling Thunder in March 1965. Planes attacked the Ho Chi Minh Trail, a network of roads, paths, and bridges from North Vietnam through Cambodia and Laos into South Vietnam. North Vietnamese troops used this route to bring equipment south. Other planes targeted bridges, docks, factories, and military bases in the North.
