Something truly historic has begun Friday morning in the truce village of Panmunjom, in the Korean demilitarized zone. The leaders of the two Koreas, Kim Jong-un and Moon Jae-in met in the morning to start a much anticipated summit.

The two cordially greeted one another with a handshake and holding hands, Kim led Moon across the demarcation line within the summit building, crossing into North Korea, then returning back to the Southern side for the talks.

Ceremonies and talks are planned throughout the day, with everything planned down to the minute. The visit marks the first time a North Korean leader has ever entered South Korea. Months of feverish diplomatic efforts have brought decades of acrimony to a virtual halt, and made these talks possible.
