Trump says it’s fine for Trump to insult anyone he feels like insulting, but not the other way around. That’s Justice According to Toddlers.

Of course, there is damage to relations between the UK and the Trump White House too.

Mr Trump likes to dish out insults and criticism (remember his frequent belittling of Theresa May over Brexit, and his all out verbal attacks on the mayor of London) but he is pretty thin-skinned when the verbal arrows are aimed at him.

“Pretty” thin-skinned? He goes ballistic at the smallest criticism and even disagreement.

As the Foreign Office launched an investigation into the source of the leak to the Mail on Sunday, Mr Trump told reporters in New Jersey: “We’re not big fans of that man and he has not served the UK well.

“So I can understand it and I can say things about him but I won’t bother.”

What he actually said was

You know, we’ve had our ins and outs with a couple of countries, and I would say that the UK and the ambassador has not served the UK well. I can tell you that. We’re not big fans of that man and he has not served the UK well. So I can understand it and I can say things about him but I won’t bother.

Yes, he said the UK has not served the UK well. The BBC left that bit out but you can hear it if you play the first clip.
