Going into this bilateral summit, those around Sir Keir Starmer were stressing that these guys genuinely got on well, they liked each other, and that the prime minister could say things to Mr Trump in private and not get his head blown off.
One key element for the UK side was convincing Mr Trump to give security guarantees for Ukraine in any kind of peace deal with Russia, but he didn't really bite on that topic.
That would be a huge win for a prime minister who did not necessarily think he would come out with that, and also for a UK government that really needs to strengthen trade ties with the US because they're looking for economic growth.
Politics latest: Trump tells Starmer UK may get 'great' trade deal.
What we saw today was a genuine rapport between the two men, and Mr Trump seems amenable to Sir Keir.
