After the French left, he gave strong financial support to the new state of South Vietnam. He supported military coups in Iran and Guatemala orchestrated by his own administration. During the Suez Crisis of 1956, he condemned the Israeli, British, and French invasion of Egypt, and he forced them to withdraw. He and brother Edgar both wanted to attend college, though they lacked the funds. They made a pact to take alternate years at college while the other worked to earn the tuitions.Edgar took the first turn at school, and Dwight was employed as a night supervisor at the Belle Springs Creamery. When Edgar asked for a second year, Dwight consented and worked for a second year. At that time, a friend 'Swede' Hazlett was applying to the Naval Academy and urged Dwight to apply to the school, since no tuition was required.
