In 1951 the United States government passed a law requiring all men between the ages of 18 to 26 to register for the draft. During the Korean War (1950-1953) 80,000 men attempted to dodge the draft. During the Vietnam War (1955 – 1975) over 570,000 men dodged the draft, 210,000 of them were formally accused, and 3,250 were imprisoned. (Side note, 58,000 US soldiers died in the Vietnam War, over 1 million North Vietnamese and Viet Cong fighters died, and an estimated 2 million civilians died.)
This video looks at some of the ways men avoided the draft. They include moving to Canada, failing physical exams on purpose, becoming missionaries, or, as claimed in a 1977 interview with alt-right demigod Ted Nugent, taking drugs, acting insane, and urinating and defecating on himself before appearing for his examination (Nugent later said lied in the interview).
