Foreign governments are going to be poring through all these Donald Trump tweets looking for - to try and discern what it means for foreign policy.

I've never been much drawn towards satire of any kind. I don't like that style whereby you kind of stitch people up. But the deeper thing is that I just find these people so impressive and admirable.

[William] Eggleston's photographs look like they were taken by a Martian who lost the ticket for his flight home and ended up working at a gun shop in a small town near Memphis. On the weekend he searches for the ticket - it must be somewhere - with a haphazard thoroughness that confounds established methods of investigation.

If Donald Trump thinks that just by being unpredictable that somehow he can have an impact, but not necessarily commit himself to certain things, that's not the way it is going to be read in foreign capitals. Foreign governments are going to take these things very literally and very directly.

The thing that strikes me, from looking at the names so far in the Donald Trump's Cabinet on the foreign policy side, is the one thing that unites them - and that's General James Mattis at the Pentagon, Mike Pompeo at the CIA, even Mitt Romney to become secretary of state - they're all very, very hawkish on Iran.

In foreign countries, when people see what Donald Trump is saying on Twitter since the election and seeing what he's saying in these calls with foreign leaders, they take everything very seriously and they take everything very literally.

I don't like my books being defined by their "about"-ness. So now the subtitle has just become a kind of strap-line on the cover.
