Yes, even dictators get cold feet.

Wednesday’s news that North Korea was considering calling off Kim Jong-un’s planned June meeting with President Trump reflected a pattern by the unpredictable regime: diplomatic outreach, followed by erratic behavior and, in many cases, an outright rejection of peace overtures.

Dashed hopes at six-party talks

After its withdrawal from the Nuclear Nonproliferation Treaty, North Korea agreed to take part in six-party talks with the United States and regional powers, and pledged in 2005 to “abandon nuclear weapons and existing nuclear programs.” But the following year it conducted its first nuclear test.
