After America's defeat of Japan in World War II, the French continued its colonial rule in Vietnam until 1954 when the Vietminh, Ho Chi Minh's communist army, defeated it once and for all. In response, the American President Dwight D. Eisenhower imposed a demilitarized zone on Vietnam that split the country into two and effectively delineated a civil war boundary between the Northern communists under Ho Chi Minh's rule and the Southern nationalists under Ngo Dinh Diem. The United States intervened in Vietnam from 1945 to 1054 to maintain an alliance with the French, to guard its(the American) economic interests, and to stop the domino theory that (domino theory or Domino Theory?) predicted the regional spread of communism from one region to another.
In January of 1944, President Roosevelt noticed the importance of Vietnam in regards to U.S. interests(what interests? Economic?), but he also realized that the country was already firmly under French colonial rule. Because of that, the United States chose to use its influence to help France to improve conditions in Indochina that "in the face of British and French resistance, he(who? Replace "he" with "[name]") now spoke only of limiting French control rather than establishing an international trusteeship" (State Department). Under French and British resistance, President Roosevelt did not want to lose important allies so he agreed to let the French continue its colonial rule on Vietnam. The statement clearly shows the American's ambition on Indochina and Vietnam. (need an introduction to the quote)"But now was the time for us to cooperate wholeheartedly with France" (State Department). The United States provided support in the form of weapons, bombs, money, etc to French military. (intro)"In October 1949, US policy moved swiftly to full-scale material support of the French war against the Viet Minh" (Sponsoring French Colonialism).
