I’m no expert but it seemed that the big oversight in Brexit was that a war on UK’s border was put on hold in the 90’s due to the fact that the EU made borders within Europe pretty inconsequential. The backstop was Theresa May’s attempt at solving the problem of both having a border and not having a border, by basically not leaving the EU. Talk of the EU “punishing” the UK is silly. The EU is not going to renegotiate a huge set of treaties (the leaving agreement) due to the fact that the UK can’t find a way to both have a border and not have a border. They just spent 2 years negotiating with the UK and now the UK has gotten cold feet.
