The victims included 1.5 million children and represented about two-thirds of the nine million Jews who had resided in Europe. Some definitions of the Holocaust include the additional five million non-Jewish victims of Nazi mass murders, bringing the total to about 11 million. Killings took place throughout Nazi Germany, German-occupied territories, and territories held by allies of Nazi Germany.  - Vice Admiral Emory Scott Land (January 8, 1879  November 27, 1971) was an officer in the United States Navy, noted for his contributions to naval architecture, particularly in submarine design.

It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.  - The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II.

The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.  - The War Shipping Administration (WSA) was a World War II emergency war agency of the US government, tasked to purchase and operate the civilian shipping tonnage the US needed for fighting the war.
