Britain’s decision to leave the EU wasn’t right from the moment it was voted on. Now that the secretary for Brexit has abruptly left his post in the UK, there is a chance for sanity to return. The country stood to lose far more than it gained from the rupture. It was as harebrained as Trump’s decision to begin trade wars with allies. It makes one wonder what has happened to the political world. Democracy is under threat. Strong rulers have risen to bend nations to their will. Free expression has been constrained in one country after another. Given economic strength, it should be the best of times. It isn’t.
