As Donald Trump moves from his wreckage of the G7 summit in Canada to his Tuesday face-to-face encounter with North Korea’s Kim Jong-un, I have been speaking with radio and TV about both the Trumpian demolition of alliances and the prospects for his embrace of Kim:

A 15-minute discussion with Eamonn Holmes and Christopher Biggins which starts with the summits and goes farther to consider how Trump’s character, reality TV, and even professional wrestling shape the President and the current international climate.

Donald Trump will get his picture, his historic meeting. The North Koreans will get their symbolism that they are no longer in isolation, that they are coming out politically and economically as part of Asia.

Both sides get their symbolic victory, but the whole question of “denuclearization” — there won’t be any definition of that.

I am extremely worried. We are now at the point where White House advisors are saying there is a “special place in hell” for Canadian Prime Minister Justin Trudeau and other foreign leaders, and that they “stabbed us in the back”.

We are at the most serious point in US-European and US-Canadian relations since 1945. While Trump is in office, either Trump wins or the alliances. You cannot have both.

The opening question: “Is Donald Trump a strong or a stupid man?”, followed by “Isn’t Donald Trump serving American interests?”

US foreign policy has been founded for more than seven decades on the notion of alliances with European countries, with Asian countries, with Canada, with Mexico. It is no longer founded on alliances but on Donald Trump’s ego, and it will change depending on whether Donald Trump is happy or unhappy with Europe.

There’s a further discussion of the risks for Trump as he enters talks with Kim Jong-un without any other officials in the room.

A brief discussion on BBC Talkback — the other panellist is Sarah Elliott of Republicans Overseas UK — on whether “Donald Trump should engage with evil regimes”:

Sometimes, in international diplomacy, you have to deal with some nasty characters. The question is how you engage with them: with eyes open, with ears open, and often with mouth shut.

The concern here is that Donald Trump is walking into this to have a picture with Kim Jong-un, not because of a clear strategic approach to North Korea. Trump himself has said that there has been no preparation with meetings in the White House.

These are issues that have occupied diplomats for many years, but Donald Trump thinks that in a heartbeat — or with a flick of his fingers — this will all change.

Even with the smartest of Presidents, the most sophisticated of Presidents, this would take months, even years, as we saw at the end of the Cold War with the Soviet Union. For someone like Donald Trump, who doesn’t always show the sharpest grasp of reality, the difficulties will be far greater.
