Pacific War - Deadly Dozen

When the attack on Pearl Harbor occurred, the United States was not at war anywhere in the world. The America First Committee, 800,000 members strong, had vehemently opposed any American intervention in the foreign conflict, even as America provided military aid to Britain and the Soviet Union, through the Lend-Lease program. Opposition to war in the United States vanished after the attack. Four days after Pearl Harbor, on December 11, in a massive strategic blunder, Nazi Germany and Fascist Italy declared war on the United States, drawing America into a two-theater war.
