The document discusses several key questions around the Vietnam War:
1) Vietnam was divided along the 17th parallel in 1955 with North Vietnam led by Ho Chi Minh becoming communist and South Vietnam led by Ngo Dinh Diem becoming a US-backed republic.
2) The US became involved to stop the spread of communism in Southeast Asia and initially sent 16,000 troops by 1963, but involvement escalated greatly over the following years.
3) Many Americans, especially younger people and those in the counterculture movement, opposed the war due to the mounting death toll, civil rights issues, and social changes happening in the US.
