After American troops defeated the Japanese in the Battle of Iwo Jima, they had one last destination. In the last battle of WWII, the Americans and Japanese fought nonstop for 2 months until the US eventually won. This victory at Okinawa allowed the allies to be able to invade Japan and finally end the war.

Manhattan Project

Instead of invading Japan, the US had other plans. German American Albert Einstein warned Roosevelt of the existence of atomic bombs and how they might already be experimented on in Germany. In the Manhattan Project, scientists worked together to form an atomic weapon that had the ability to wipe out whole cities. President Truman was faced with a conflict: invade Japan or bomb them. It made much more sense to bomb the Japanese than to risk US lives in another battle. After Japan continuously refused to surrender the war, the US bombed Hiroshima and Nagasaki. The Japanese eventually surrendered.

Casablanca Conference

In January of 1943, President Roosevelt and Prime Minister Churchill met in order to plan the end of the war. It was concluded that the Allies resolve conflicts with Germany to maintain postwar peace and have a policy of unconditional surrender. Their main goal was to prevent whatever happened after WWI that caused WWII.

Tehran Conference

In late November and early December of 1943, the 3 Allied leaders held a meeting for the first time after the war ended. Together, Stalin, Churchill, and Roosevelt decided the fate of Europe. One of the agreements that they decided on was to assist the Soviet Union by opening another front where they were still in conflict with the Nazis.
