Donald Trump has become the first sitting US president to set foot in North Korea, after meeting Kim Jong-un in the area dividing the two Koreas.
Mr Trump and the North Korean leader posed for handshakes before talking for nearly an hour in the heavily fortified demilitarised zone (DMZ).
Both countries agreed to set up teams to resume stalled nuclear talks.
Their last summit broke down in February with no progress on denuclearisation in North Korea.
Critics have dismissed the occasion – the two leaders’ third face-to-face encounter in just over a year – as a political theatre and say North Korea still needs to show that it is serious in getting rid of its nuclear weapons.
I completely agree that it was theater and that NK needs to demonstrate its sincerity. I disagree that the encounter was meaningless. Symbols and images can be very powerful. Certainly, the evil butterball (as Jay Weber calls Jong-un) is susceptible to it. So we’ll see… maybe this is another step toward peace. Maybe it is one more in a decades-long series of false starts.
