USA HISTORY

Detailed explanation-1: -On December 7, 1941, following the Japanese bombing of Pearl Harbor, the United States declared war on Japan. Three days later, after Germany and Italy declared war on it, the United States became fully engaged in the Second World War.

Detailed explanation-2: -During the 1930s, the combination of the Great Depression and the memory of tragic losses in World War I contributed to pushing American public opinion and policy toward isolationism. Isolationists advocated non-involvement in European and Asian conflicts and non-entanglement in international politics.

Detailed explanation-3: -Isolationism refers to America’s longstanding reluctance to become involved in European alliances and wars. Isolationists held the view that America’s perspective on the world was different from that of European societies and that America could advance the cause of freedom and democracy by means other than war.

Detailed explanation-4: -Although U.S. isolationism was not the only cause of WWII it was one of the main reasons for the start of the war because it allowed authoritarian rule to sweep the world with the weakened League of Nations, contributed to the worsening of the Great Depression, and made diplomatic resolve abroad impossible.
