David Zeiger was a college kid organizing protests against the Vietnam War. Now, as a documentary filmmaker, Zeiger explores one aspect of the anti-war protests not widely publicized today: the role of active-duty GIs and veterans in protesting the war, from objectors who faced court-martial to veterans recounting atrocities they say were sanctioned by the Pentagon. Zeiger combines interesting archival footage (such as some political-theater skits featuring Jane Fonda) and touching interviews with veterans and protesters, and suggests how forces have rewritten history to drive a wedge between Vietnam veterans and the protest movement. (For example, one interviewee argues the iconic image of protesters screaming "baby killer" at disembarking soldiers was an urban legend.) Zeiger presents a trippy alternative history that prompts questions about what today's troops in Iraq might be thinking.
