[195][196] However, Kennedy, who was wary about the region's successful war of independence against France, was also eager to not give the impression to the Vietnamese people that the United States was acting as the region's new colonizer, even stating in his journal at one point that the United States was "more and more becoming colonists in the minds of the people."A year and three months later on March 8, 1965, his successor, President Lyndon Johnson, committed the first combat troops to Vietnam and greatly escalated U.S. involvement, with forces reaching 184,000 that year and 536,000 in 1968.[197]
In late 1961, Kennedy sent Roger Hilsman, then director of the State Department's Bureau of Intelligence and Research, to assess the situation in Vietnam. There, Hilsman met Sir Robert Grainger Ker Thompson, head of the British Advisory Mission to South Vietnam, and the Strategic Hamlet Program was formed. It was approved by Kennedy and South Vietnam President Ngo Dinh Diem. It was implemented in early 1962 and involved some forced relocation, village internment, and segregation of rural South Vietnamese into new communities where the peasantry would be isolated from communist insurgents.
