Answer: The right answers are Italy, Germany, and Japan.
Explanation: Just to elaborate a little bit on the answer, it can be added that Great Britain and France were Allied powers. Germany, Italy, and Japan, on the contrary, were Axis powers, and they were ruled, respectively, by three dictators: Hitler, Mussolini (who coined the term "Axis" powers), and Emperor Hirohito. The United States declared war against Japan, Germany, and Italy in December of 1941.
