6 agos 1945 año - Hiroshima bombing
Descripción:
 An atomic bomb was dropped on the Japanese city of Hiroshima by the US. About 140,000 people died.
The Cold War concept that this event matches is deterrence. This is because this use of an atomic bomb warned any other countries not to attack the US, as they wouldn't hesitate to nuke them.
