The [[Kennedy]] administration, which had repeatedly intervened to halt right-wing coups, acquiesced in 1963 to the overthrow of South Vietnam's Diem by a coalition of generals. President Nixon would later characterize this decision as a catastrophic betrayal of an ally that contributed to the ultimate disintegration of South Vietnam. The casus beli for the United States intervention was an alleged attack on a US ship by North Vietnam, the Gulf of Tonkin Incident. The US responded with a massive bombing campaign called Operation Rolling Thunder. Although a swift victory over North Vietnam would have taken a matter of months, the risk of Chinese intervention was considered too great to accept. Thus, Vietnam was fought to avoid "another Korea". | The [[Kennedy]] administration, which had repeatedly intervened to halt right-wing coups, acquiesced in 1963 to the overthrow of South Vietnam's Diem by a coalition of generals.
