Weapons of mass destruction. A comprehensive approach

Ever since 1947, the Bulletin of the Atomic Scientists’ ‘doomsday clock’ is recognized as a symbol for the nuclear threat in the world. The minutes before midnight on the clock demonstrate the actual threat. Since the beginning, the clock’s arm has been moved back and forth, whenever the nuclear threat situation in the world changed. At the end of the Cold War the clock stood at seventeen minutes to midnight, while at the last presentation, in 2007, the clock was ticking five minutes to midnight.
