This is how it works in Trump world.
The US president arrives at a party, causes a fuss, breaks some crockery, and leaves everyone stunned.
Then as the dust settles, he declares what a good time he has had, how it’s all been a great success, while offering a few words of apology for the disruption caused. So it was at the Nato summit, and so it was during his visit to Britain.
Mr Trump used his interview in the Sun to throw a few plates at Theresa May, criticising her Brexit strategy, threatening to block a trade deal with the US, praising Boris Johnson. Cue outrage and much gnashing of teeth.
Then came the news conference at Chequers where the president revealed he had apologised to the prime minister, praising Mrs May as an “incredible woman… doing a fantastic job… a terrific woman”, insisting the UK-US relationship was “the highest level of special”, all the while accepting that a trade deal might be possible just so long as there were no “restrictions” on US firms.
And so it goes: the UK-US relationship settles back on to an even keel and life returns to normal. That, at least, is the hope of British officials.
They designed this trip to show Mr Trump the depth of the relationship between the UK and the US: the history of Blenheim and Churchill, the dinner with business leaders who create jobs in America, the special forces who co-operate in the fight against terrorism, the Queen who has met 11 of Mr Trump’s predecessors.
The symbolism was clear: the ties that bind Britain to the US are long and deep.
