The years 1940 and 1941 were a tumultuous time for the world. In Europe, the Second World War had been raging for nearly a year, with Nazi Germany having conquered much of the continent. In the Pacific, Japan had been expanding its empire, and had begun to threaten the United States.
In the United States, the public was divided on how to respond to the war. Some wanted to stay out of the conflict, while others wanted to join the fight against the Axis powers. President Franklin D. Roosevelt, however, was determined to aid the Allies in their fight against the Axis.
In 1940, the United States began to provide aid to the Allies, including Britain and France. This aid included food, weapons, and other supplies. The United States also began to build up its own military forces in preparation for a possible entry into the war.
In 1941, the United States began to take a more active role in the war. In June, the United States declared war on Japan after the Japanese attack on Pearl Harbor. This was followed by a declaration of war on Germany and Italy in December.
The United States now joined the Allies in the fight against the Axis powers. The United States provided much needed supplies and manpower to the Allied forces, and helped to turn the tide of the war.
By the end of 1941, the Allies had gained the upper hand in the war. The Axis powers were on the defensive, and the Allies were beginning to push them back. The tide of the war had begun to turn, and the Allies were now on the path to victory.
