The outcome of the new election is very revealing because it shows what the Brits are thinking.
The message I got from this new referendum is that the English don't want a second referendum. They just want an end to Brexit. The Scots have shown that they prefer the EU to the UK. The United Kingdom isn't important to many of them but staying in the EU is. The SNP have increased seats. Northern Ireland is heading the same way. They want the EU more than the UK and they feel betrayed by British Parliament.
What happens in the 2020s and beyond is only known by the gift of hindsight. No one can guess what the near future will be like.
