Ubico saw the United States as an ally against the supposed communist threat of Mexico, and made efforts to gain its support. When the US declared war against Germany in 1941, Ubico acted on American instructions and arrested all people in Guatemala of German descent. He also permitted the US to establish an air base in Guatemala, with the stated aim of protecting the Panama Canal. However, Ubico was an admirer of European fascists, such as Francisco Franco and Benito Mussolini, and considered himself to be "another Napoleon". He occasionally compared himself to Adolf Hitler. He dressed ostentatiously and surrounded himself with statues and paintings of Napoleon, regularly commenting on the similarities between their appearances. He militarized numerous political and social institutions—including the post office, schools, and symphony orchestras—and placed military officers in charge of many government posts.
