What a difference a year makes.

In a scene that would have been unthinkable just nine months ago, photos released Sunday showed North Korean leader Kim Jong Un making the popular "finger hearts" gesture atop Mount Paektu — one of the Koreas most sacred sites — with top South Korean officials.

The pictures, released by South Korea's presidential Blue House, showed a beaming Kim posing while attempting the gesture in front of the mountain's pristine crater lake on Thursday.
