1945


 * The first Human-Made nuclear weapons are used against an enemy, when the United States drops two atomic bombs on the Empire of Japan.
 * As World War II draws to a close, Franklin D. Roosevelt, Adolf Hitler, Benito Mussolini, and General Patton, all leaders of the war, die.
 * The end of World War II, the bloodiest and most expensive war in Human history up to that point.
 * The United Nations is formed on Earth at the end of a years-long intercontinental war: World War II. The UN eventually forms the UNSC in the 2100s, but the UN begins embarking on military and security operations as early as the 1950s. Fifty-one nations originally signed the UN Charter, which governed the "global association of governments facilitating co-operation in international law, international security, economic development, and social equity." By the beginning of the 21st century, practically all the nation-states on Earth are members of the United Nations.
