One way or another, a major chapter in Britain’s history is about to be written. President Trump should help to make sure it’s a positive one.

I note this in light of British Prime Minister Theresa May’s presentation to her Cabinet on Wednesday regarding her newly agreed deal with the European Union. The deal, which requires parliamentary support, will hopefully set the terms of Britain’s withdrawal from the EU in March 2019. But fraught with deep political controversy and risk, May’s plan will find resistance from a mix of parliamentarians. There will be those who oppose Brexit on any terms, others who oppose Brexit on May’s terms, and those who see this as an opportunity to bring down May’s government. Regardless, the simple fact is that May will have an almighty struggle getting this deal out of Parliament and into law.
