In May 1961, JFK had authorized sending 500 Special Forces troops and military advisers to assist the government of South Vietnam. They joined 700 Americans already sent by the Eisenhower administration. In February 1962, the president sent an additional 12,000 military advisers to support the South Vietnamese army. By early November 1963, the number of US military advisers had reached 16,000.
Even as the military commitment in Vietnam grew, JFK told an interviewer, "In the final analysis, it is their war. They are the ones who have to win it or lose it. We can help them, we can give them equipment, we can send our men out there as advisers, but they have to win it—the people of Vietnam against the Communists. . . . But I don't agree with those who say we should withdraw. That would be a great mistake. . . . [The United States] made this effort to defend Europe. Now Europe is quite secure. We also have to participate—we may not like it—in the defense of Asia." In the final weeks of his life, JFK wrestled with the need to decide the future of the United States commitment in Vietnam—and very likely had not made a final decision before his death.
