Answer 1

"In the early 1960s, most Americans actively supported the war. In the second half of the decade, their support decreased."

Briefly: U.S. involvement was initially backed or accepted by a majority, but as casualties, televised coverage, and events like the Tet Offensive eroded confidence, public opinion shifted toward opposition by the late 1960s.
