Guess who has the most nuclear weapons? Hint it's not the US

More than half a century has passed since a nuclear weapon was used on battlefield. In August 1945, the US detonated two nuclear bombs, code-named "Little Boy" and "Fat Man", over Hiroshima and Nagasaki in Japan. The bombings resulted in the death of over 1,20,000 people. Despite the restive calm of the intervening years, many countries have been ramping up their nuclear stockpiles to be better prepared if the sceptre of war rears its head once again.

In the event of a future conflict, nations that have attained breakout could have an undue advantage, with nuclear warheads being used to augment their capabilities in conventional warfare. The exact number of nukes in each country's arsenal remains closely guarded. Here is a list of countries that have an arsenal of nuclear-powered missiles, according to data compiled by the Stockholm International Peace Research Institute, the Arms Control Association and the Federation of American Scientists.
