I expected the US-NK talks to be thin on detail. I didn't expect Trump to capitulate unreservedly to all of Kim's demands, in exchange for a boatload of bones. But that's basically what he's promised.
Of course, we've seen before that what he promises and what he does are two quite orthogonal things. Just ask Mr Trudeau.
But at this point, he's shaken the hand of another despot, and pronounced the South Korean and Japanese alliances dead. Not for the first time, he's signalled that the USA has no real interest in what goes on around the Pacific Rim. South Korea and Japan now have two options: to apply to the Chinese for protection, with whatever foreign policy shifts that might entail; or to develop their own nukes, because clearly that's the only thing America respects.
But not to worry. There are very, very few countries in the world with less resources than North Korea - which suggests that if they can build a nuclear capability to hit the US mainland, anyone can. We'll see how Mr Trump feels about countries taking responsibility for their defence when Venezuela gets the bomb.
Don't it just make you feel safe?
