In a historic summit that few could have imagined just months ago, North Korean leader Kim Jong Un and South Korean President Moon Jae-in announced Friday the opening of "a new era of peace" that would end the Korean War and achieve a nuclear-free Korean Peninsula.

But the grandiose pronouncements in the so-called Panmunjom Declaration was scant on details about how this would actually be done and mirrored a previous vow to rid the Korean Peninsula of nuclear weapons.

Indeed, the two Koreas had agreed to denuclearize the peninsula and establish a permanent peace there in their two previous summits in 2000 and 2007.
