The nuclear bomb was first used for one of the biggest terrorist actions in the history of humankind. As per the definition given by the UN panel, on March 17, 2005, terrorism is as any act "intended to cause death or serious bodily harm to civilians or non-combatants to intimidate a population or compel a government or an international organization to do or abstain from doing any act.” The purpose of bombing of Hiroshima and Nagasaki on August 6th and 9th of 1945, that killed millions of civilians instantly, and killed many more painfully over the years, was only to intimidate the Japanese government into submission. It was indeed the most gruesome act of terrorism in the history of humans.
