All-Out Trade War?

Johnson and the Northern Ireland protocol:

All-out trade war with the EU? Most people in the UK don't want it and even 2016 no-one voted for this. Back then it was "no-one is talking about threatening our place in the Single Market."
Now there is an ultra-right-wing Tory party trying to make the insane idea of Brexit work. I predict more burning buses in Belfast and fishermen etc getting really really angry...
