I may not do it. Nobody knows what I'm going to do".

He let the world believe he had agreed a two-week pause to allow Iran to resume negotiations. And then he bombed anyway.

A pattern is emerging: The most predictable thing about Trump is his unpredictability. He changes his mind. He contradicts himself. He is inconsistent.

"[Trump] has put together a highly centralised policy-making operation, arguably the most centralised, at least in the area of foreign policy, since Richard Nixon," says Peter Trubowitz, professor of international relations at the London School of Economics.

"And that makes policy decisions more dependent on Trump's character, his preferences, his temperament."
