July 10, 1940-June, 1941 The Battle of Britain, in which Royal Air Force fighters defend the islands against massive Luftwaffe bombing raids on all major cities in England and Ireland. Large-scale civilian casualties.
July-August 1940 Playwright Murray Burnett collaborates with Joan Allison to write the stage play, Everybody Comes to Rick's. In New York, they found no producers willing to back the play, which was never performed or published, but they sold the script to Warner Brothers for $20,000. To this day, the text of the play remains the property of the studio.
March 11, 1941 President Roosevelt signs the "Lend Lease Bill," authorizing Great Britain to purchase weapons and other materials while deferring payments until after the war, effectively ending United States "neutrality," though America still has not declared war. By April, U.S. Navy patrols are in defensive actions against German submarines in the Atlantic.
June 22, 1941 Luftwaffe bombing raids over England stop when Germany sends the planes east, breaks its non-aggression pact with the Soviet Union and invades it, reaching Moscow by October. Although U. S. warships have been fired on and the destroyer Ruben James has been torpedoed by a U-boat (10/31/41), American still has not declared war.

In the same month, the U.S. launches the "Doolittle Raid," American B-25 bombers on a one-way mission from aircraft carriers off Japan to bomb Tokyo and other industrial cities before landing in China or ditching in the sea. This action, and the naval victories in the May "Battle the Coral Sea" and June "Battle of Midway," are major propaganda victories for Americans demoralized by losses. In June, Japan attacks Dutch Harbor in the Alaskan Territories, and on June 18, America secretly begins the Manhattan Project to develop an atomic bomb.
