False starts and failures on North Korea: the long road to the planned summit between Donald Trump and Kim Jong-un
Since the end of the 1950-53 Korean war, relations between the Koreas have been marked by wild swings, with three historic summits mixed with hostility that often pushed the rivals to the brink of a major conflict

No, North Korean leader Kim Jong-un isn’t killing his summit with US President Donald Trump. Or at least, he’s highly unlikely to.
Washington and Seoul, which have no intentions to overpay for whatever Kim brings to the table, have been saying strengthened international sanctions forced Kim into talks after a flurry of weapons tests.
Pyongyang has now countered by saying it won’t be unilaterally pressured into abandoning its nukes, analysts say.
Nonetheless, North Korea’s surprise declaration on Wednesday was a fresh reminder of many false starts and failures that derailed previous diplomatic attempts to resolve the decades-long stand-off. It’s also a frustrating development for South Korea, which has been selling last month’s inter-Korean summit – where the leaders issued a vague vow for the “complete denuclearisation” of their peninsula – as a meaningful breakthrough in peace.
