On Sunday, Secretary of State Mike Pompeo is headed to Pyongyang to set up the details for another meeting between President Trump and North Korean dictator Kim Jong Un. Pompeo has a hard road ahead of him and will be essentially playing wingman for a difficult but potentially important second date between the two leaders.

One key difficultly is that North Korea keeps changing its demands of Washington. Currently, Pyongyang says that another meeting isn’t enough and that Washington must prove its trust and seriousness (or is it love?) by reducing sanctions.
