There's no place on Earth like North Korea
Its citizens are closed off from the rest of the world, mostly impoverished and only allowed to access state-run propaganda.
Its government is armed to the teeth with the world's fourth-largest standing military, chemical weapons, highly-trained special forces and now, nuclear weapons -- which the regime believes are the key to its survival.
But after years of isolation, the country's leader, Kim Jong Un, has now expressed a willingness to engage in diplomacy and put denuclearization on the table.
Is he sincere? Or is he just buying time to put the finishing touches on his nuclear program?
