What was included? Very little. Apart from the too-thin nuclear clause, there was a promise to "establish new relations" between the US and the DPRK, to jointly work to build "a lasting and stable peace regime" on the peninsula – whatever that means – and to return any POW or missing in action remains to their country of origin. That's it.
The only real concession made came outside the summit after the agreement was signed, when President Trump announced the cancellation of all future allied "war games" in the region.
Whether this includes any with Japan was not immediately clear, but to say the South Koreans were dismayed at this unexpected lead balloon is understatement.
Why did the man famed for penning The Art of the Deal throw such a large bone to Chairman Kim?
There are two schools of thought. One is that the whole summit process was whipped up merely in order to show the folks back home what a great statesman Trump is, rising above all the mutual name-calling and promised destruction volleyed back and forth in previous months, and this extra was to demonstrate how magnanimous he could be with people – even enemies - who made a show of going along with him.
Traditional allies of the G7, take good note!
The other – which is not mutually exclusive – is this is Trump's way of taking the moral high ground, so that whatever action may be held to be necessary in future when the so-called "deal" falters can be blamed on North Korea, who will always be painted as the "bad sports".
Kim Jong-un is doubtless basking in the glory of what he sees as a diplomatic coup that helps legitimise his rule, but I suspect he's been sucker-punched; for all he is a dictator, he needs to understand that in essence Trump is a mobster, with a mobster's instincts and way of resolving problems.
I suggest Trump's "no exercises" offer was not a laurel leaf; it's designed to hook China into backing the US position by giving China everything it wants.
That's very crafty because if there's one thing the Chinese try to avoid above all else, it's losing face. When, as seems almost inevitable, push comes to shove over Korea, China may find itself too compromised to back its puppet-ally further.
At which point, the US wins. And, strange as it sounds, then Trump will, via his own kiss-of-death version of mobster diplomacy, have proved himself a genuine statesman.
As much as I had trouble writing that, you read it here first!
