Lyndon Johnson's War? Part I: Escalation

Abstract

At the beginning of 1964 there were around 20,000 US military ‘advisers’ in South Vietnam, working alongside the South Vietnamese army in the latter's campaign against the communist guerrillas, led and supplied by the government of North Vietnam. By the summer of 1965 there were 125,000 American troops in the country, with more pledged for future deployment. Most of these were not ‘advisers’, but combat forces openly engaged in fighting the communists. In addition, since March 1965, a sustained American bombing campaign had been waged against targets in North Vietnam. This transformation in the nature of the American commitment to South Vietnam had been brought about by two factors: the continued weakness of South Vietnamese governments as military and civilians struggled for control; and the growing strength and success of the communist guerrillas. South Vietnam was regarded as a vital American interest for two reasons: it was perceived as a test of US resolution throughout the rest of the world; and, following the famous ‘domino theory’, it was believed that the loss of South Vietnam to communism would precipitate the weakening and eventual collapse of other non-communist states in the region. Although there was opposition to the escalation of the war, both in Congress and the administration, there were also voices notably in the military, who wished to press on further and faster. The administration adopted a middle course, gradually increasing its commitment and continually planning for the next step. Although political motives undoubtedly played a part in this more measured approach—there was a presidential election in November 1964—it is clear that President Johnson was not at all convinced that any policy he chose would save South Vietnam. At the same time, he feared the consequences of withdrawal, both at home and abroad. A deeply insecure man, he allowed himself to be persuaded by his principal advisers, to whom he felt indebted for personal as well as political reasons.
