This thesis examines the policy that the United States utilized between 1945 and 1950 to enlist Dutch support for post-war European organizations and the place of this relationship within United States overall Cold War policy. The Netherlands willingness to cooperate and further United States objectives significantly contributed to the development of economic reconstruction and military security in Western Europe. In addition the United States unprecedented vision for a multilateral defense treaty came to fruition in part through Dutch support and compliance. However, the Dutch also had to make some historic changes. The United States opposed the Dutch attempt to retake Indonesia forcing the Dutch to choose security in Europe over their colony. Sources include memoirs of principal participants as well as United States and Netherlands governmental documents relative to foreign relations.
