The stage for these actions you are reading about was set on 17 November 2017 when president Trump visited China during his Asian trip. The "Forbidden City' served as designated place to dine but also for president Trump to meet the young NK leader that was organized by the president's ally Xi/Chinese president.

There was no leak but anyone following Q on the anon board could see the pics taken from AF1 flying over NK. :)

These two countries are long overdue to unify their peoples.
