The world's nuclear club is an exclusive group – and it has become even more dangerous with the relatively recent and unwelcome addition of North Korea and its leader, Kim Jong Un.
The United States wants the rogue regime to give up its nuclear-weapons ambitions, and President Donald Trump aims to achieve that goal, possibly through direct diplomacy. The White House said Friday that Trump still intends to meet Kim by the end of May, following his on-the-spot acceptance of an invitation to talk.
It might be too big a demand, however. North Korea is the only country to test nuclear weapons this century, and Kim has emphasized that nuclear weapons are a fundamental part of his regime's national security. And so the potential summit puts into motion the most significant development in years of intermittent negotiations about North Korea's nuclear weapons program.
North Korea is one of nine nations to have stockpiled nuclear weapons – about 14,500 total worldwide, a figure that has declined since the Cold War.
