The Battle of the Coral Sea was a major naval battle fought between the Imperial Japanese Navy and naval and air forces from the United States and Australia. It took place from May 4 to May 8, 1942, in the Pacific Theater of World War II. The battle was significant as it was the first time in history that two opposing naval forces engaged in combat without directly sighting each other. Instead, the battle was fought entirely through aircraft carrier-based planes, marking a new era in naval warfare. The battle ultimately resulted in a tactical victory for the Japanese, as they sank more Allied ships than they lost, but it was a strategic victory for the Allies. This was because the battle halted the Japanese advance towards Australia and prevented them from seizing Port Moresby, which would have threatened Allied positions in the Pacific.

The Nuremberg Trials were a series of military tribunals held after World War II to prosecute prominent leaders of Nazi Germany. The trials were held in the German city of Nuremberg from November 20, 1945, to October 1, 1946. The purpose of the trials was to hold individuals accountable for war crimes, crimes against humanity, and other atrocities committed during the war. The defendants included high-ranking Nazi officials, military officers, and members of the SS. The trials set a precedent for international law and established the principle that individuals can be held responsible for their actions, even during times of war. The Nuremberg Trials brought attention to the Holocaust and the extent of Nazi crimes, helping to shape public opinion and pave the way for future trials and the establishment of the International Criminal Court.
