Sixty-five years after the Korean War ended in an uneasy truce, there is still no formal peace treaty between the two Koreas. Nor does one exist between North Korea and either the United States or Japan.

In 2017, it seemed that war with North Korea was a possibility after Pyongyang tested nuclear devices and launched a series of missiles. This year, however, North Korean leader Kim Jong Un shocked and confounded North Korean experts in the West and Japan with unprecedented diplomatic overtures, topped by a meeting on South Korean soil in April with South Korean President Moon Jae-in and then, last month, a historic summit with U.S. President Donald Trump in Singapore.
