For those who haven't been following along, it's fairly clear now that Britain is headed for a so-called "Soft Brexit," meaning the United Kingdom will remain inside the European customs union and maintain similar regulations and practices, but give up their direct membership in the European Union and their ability to vote on the union's decisions.
Now, Trump says his own words that were recorded on tape are "fake news," but he participated in an interview with Britain's Sun newspaper in which he attacked British Prime Minister Theresa May for choosing a soft exit.
She "didn’t listen to me" he says.
Trump chastised May for ignoring his advice on Brexit and not making a credible threat to walk away from talks.
“I would have done it much differently,” he told the Sun, which urged its readers to back Brexit before a referendum in June 2016. “I actually told Theresa May how to do it, but she didn’t listen to me.”
And how exactly would Trump "do it?"
Well, we don't know and I doubt Theresa May or Trump himself knows either, but our own experience here inside the United States tell us doing anything Trump's way means repeatedly fucking yourself.
Britain's decision to exit the European Union ("Brexit") was always a bad idea from the very beginning but, if they're going to go through with it, remaining in the European customs union is probably their best possible option.
Remaining inside the customs union will cause the least amount of disruption to business because, as a member of the customs union, goods that pass between the European mainland and the British isles will not have to pass through a customs check. The ability to bypass customs will prevent a crisis that could grind commerce to a halt.
You may ask why the hell would anyone press for a more "hard" Brexit if it could lead to a major disruption of business and the simple answer is: they're morons
The more complicated answer is that they want to completely ditch European regulations and laws even if it would mean destroying their own economy.
