By 1968 it became clear the U.S. was mired in a war it could not win.
At the end of January 1968, the North Vietnamese Army (NVA) and Viet Cong launched the “Tet Offensive” -- simultaneously attacking dozens of targets across their country. Their success demonstrated that the NVA had much more military strength and popular support among the Vietnamese people than the U.S. anticipated.
The number of U.S. troops deployed in Vietnam peaked in 1968, at 549,500. And 1968 marked the most expensive and deadliest year of the Vietnam War for the United States.
You may be familiar with the student- and civilian-led protests against the Vietnam War, which started to gain momentum and attention as early as 1964. What is less remembered today is another anti-war movement among those in the Armed Forces who began to question the morality of the war they were fighting and dying for. This GI movement eventually reached all branches of the Armed Forces, as well as veterans, and was growing both in Vietnam and among active-duty servicepeople at home.
