So, Sir Keir Starmer could just refuse to talk to Trump and deal only with Kamala Harris and Tim Walz, as they should have been elected as Trump is a convicted felon?
The problem is the UK<->US relationship is asymmetric.
So my question remains - how could the world deal with this possible situation ?
People who like their history will know that this isn't a novel possibility. Especially if you are English you should know that for a few decades, the Pope in their role as master of the universe refused to deal with the legitimate Monarchs of England for a while.
