Gradually a pattern emerges. Donald tweets, gets the headline, says why he's the greatest. Over the following days, gradual rumours leak out about what's actually happened. So, this week there's a dust-up between Trump and Erdogan, resulting in massive sanctions which will seriously hit the Turkish economy, and from which many of Erdogan's citizens will suffer far more than he will.
And now we get the background, from sources in Ankara. Yes, it is about the American bishop, held by the Turks, who Trump wants to be freed. He and Erdogan had discussed this, thought they had come to an agreement, but now Trump thinks that Erdogan has broken that agreement - so he's really hard-pedalling the sanctions. With conventional diplomacy you'd go back tot he record, the minutes, which would tell what had been agreed. But this is the great deal-maker, who can do it on his own, so pen-pushers would only get in the way...So far as the Turkish economy is concerned, it's a really expensive way to do business.
(But also another quiet little vindication of The Guardian, those remorseless peddlers of fake news, who actually provide us with the information we eed.)
