Camp David: What's changed?
That is the question that both the president and the PM knew would hang over this summit. George Bush answered it in a way that was designed to flatter his visitor (watch the news conference here), calling Gordon Brown a principled problem solver who understands the threat of terrorism, and describing him as a humorous Scotsman - not the awkward dour one that he'd been told about.
What was striking was that Mr Brown, while talking warmly about the shared history and shared values of the two countries, did nothing to return those personal compliments. He even referred to their meetings as full and frank - which is normal diplomatic code for an argument.
The signs though are that that difference in language reflects simply differing political calculations by both men. Gordon Brown wants to show his distance from George Bush, whereas the president wants to prove that the alliance with Britain remains strong, even after Tony Blair's departure.
On the substance, both men declared that they were at one on the battle against terror. Gordon Brown signalled that he'd make no announcement on the pullback of UK troops from Basra until after the publication in September of a report on the impact of America's troop surge.
For now, then, Britain and America's policies on Iraq are in step. After the autumn though, Gordon Brown has left his host, and voters at home, still guessing.
UPDATE 09:00 PM: If you watched the news conference, you may have noticed Mr Bush's warm greeting to me... He said to me, clearly remembering our last encounter, "you still hanging around?".
At a news conference in Washington last year, the day after the Iraq study group report was published, I suggested that his response would lead some to believe that he was in 'denial' about Iraq.
At the end of today's briefing, the president looked at me, sweating in the swampy conditions, and said, "next time you should cover your bald head". I made the fatal error of answering a quip with a quip: "I didn't know you cared". To which the president said, quick as a flash, "I don't". No Christmas card for me from Washington, then.
