The Defense Areas Agreement between the U.S. and Liberia entailed the US-financed construction of Roberts Field airport, the Freeport of Monrovia, and roads into the interior of Liberia. By the end of World War II, approximately 5,000 American troops had been stationed in Liberia.Akingbade, Harrison. “U.S Liberian Relations During World War II.” Phylon Vol. 46 (1). 1985. Pp 25-36. Arguments substantiating this notion are that World War II infrastructure developments did not positively affect social and political struggles in Liberia, and that decades after the development from World War II, Americo-Liberians disproportionately controlled and benefited from Liberia's growing economy and increase in foreign investment.Dalton, George. “History, Politics, and Economic Development in Liberia.” The Journal of Economic History. Vol 25(4). 1965. pp 569-591
