McIntire also gained the public eye in the early 1970s when he organized a half dozen pro-Vietnam War "Victory Marches" in Washington, D.C. The march of October 3, 1970 was supposed to have featured South Vietnamese vice-president Nguyen Cao Ky, but the Nixon administration ensured that Ky would not be present. McIntire attributed the prosecution and conviction of Lt. William Calley on 22 charges related to war crimes at My Lai to "a no-win policy" of the U.S. government in Vietnam.
