  • August 6, 1945 - The world’s second atomic bomb, Little Boy, a gun-type uranium bomb, is detonated 1,900 feet above Hiroshima, Japan. It has a yield of approximately 15 kilotons TNT. Some 90,000 to 100,000 persons are killed immediately; about 145,000 persons would perish from the bombing by the end of 1945.
  • August 9, 1945 - At 9:44 a.m., Bockscar, a B-29 carrying Fat Man, the world’s third atomic bomb, arrives at its primary target, Kokura. The city is covered in haze and smoke from an American bombing raid on a nearby city. Bockscar turns to its secondary target Nagasaki. At 11:02 a.m. the world’s third atomic bomb explosion devastates Nagasaki, the intense heat and blast indiscriminately slaughters its inhabitants.
  • August 23, 2001 - President George W. Bush announces to elementary school children in Crawford, Texas that "We [the U.S.] will withdraw from the ABM Treaty on our timetable at a time convenient to America."
  • August 29, 2007 - Six nuclear-armed missiles without any special guard are loaded onto a B52 bomber and transported from the Minot Air Force Base in North Dakota to the Barksdale Air Force Base in Louisiana. Each of the warheads mounted to the wings of the plane contain ten times the destructive power of the bomb dropped on Hiroshima in 1945. The weapons lacked special guard for more than thirty-six hours until the Air Force realizes its mistake. This flight constitutes the first nuclear-armed bomber to be flown over U.S. airspace without any upper-level authorization in nearly forty years.
