Robert Case, a 1971 University alum, photographer and activist, gave a presentation Friday recounting his experience documenting widespread protests on campus against the U.S. expansion of the Vietnam War into Cambodia in May 1970. Vietnam War expansion, campus protestsOn April 28, 1970, after half a decade of U.S. military action in Vietnam, Nixon authorized the military to expand the war into neighboring Cambodia in cooperation with South Vietnamese troops. One audience member asked Case if he was more afraid then or if he’s more afraid now. The audience member referred to Israel’s actions as genocide and asked Case about whether he thinks international solidarity is essential. “I agree with you, what you’re doing there,” Case said as he pointed to the audience member’s shirt.
