Can't say he didn't warn you. He warned Mrs May. He told her she should play hard ball and leave the EU without a deal.
He loved Boris, probably would say he still does. But Boris has got himself tangled up, just like Mrs May.
So it is with regret that the USA must leave the UK to the choppy waters of international trade and treaties without the super treaty that Trump dangled earlier.
Except, Nancy Pelosi said months ago that the Congress would never do a deal with a Parliament that left Ireland and the Irish border out in the cold. Vice President Pence said the same thing.
So what exactly did Boris expect with his solution that was no solution at all.
Trump is 'America First', and he will make sure that anyone he deals with, the UK included, learns that.
Before the referendum, some people in Britain got in a huff when Obama said that Britain would have to go to the back of the queue if it left the EU.
That was then: What crumbs of huffiness have we got with which to comfort ourselves now?
