In the 1941 State of the Union address, known as the Four Freedoms speech, President Franklin D. Roosevelt made a break with the tradition of non-interventionism. He outlined the US role in helping allies already engaged in warfare. By August, President Roosevelt and British Prime Minister Winston Churchill had drafted the Atlantic Charter to define goals for the post-war world. In December 1941, Japan attacked American and British territories with near-simultaneous offensives against Southeast Asia and the Central Pacific including an attack on the US fleet at Pearl Harbor. These attacks led the United States and United Kingdom to declare war on Japan. Three days later, Germany and Italy declared war on the United States, which the United States reciprocated.
