The leaders of North and South Korea made history Friday, shaking hands on the heavily-fortified demilitarized zone separating the two countries in the first such summit in more than a decade.

The meeting, which comes after more than five years of missile tests and threats from North Korean leader Kim Jong Un, embodied a strikingly different tone as the leaders discussed prospects for peace.

Recent weeks have seen a distinct softening in tone from the government of the northern rogue state, which has been under international sanctions for years over its ballistic missile tests, nuclear weapons development and human rights abuses. An opening of bilateral relations and denuclearization of the Korean Peninsula were the primary topics at hand.

The presidents can be seen smiling and walking together, ahead of talks during which South Korea's President Moon Jae-In hoped to convince Kim "to adopt a joint statement on the denuclearization of North Korea," according to one of Moon's advisors. Moon was elected president in 2017 on a promise of improving relations with the North, which have been hostile since the Korean War that began in 1950 and saw well over 1 million people killed.
