If I switched on the news tomorrow and the headline is “The USA has bombed…”, any country or continent could be at the end of that sentence and my surprise (or lack of) would be the same.
The USA is being run with no guard rails by a deranged dictator, backed up by white supremacists and corporate robber barons. Any country is fair game including NATO members, in response the UK should switch to a war economy.
The US is also in a civil war. Even if trumps opposition has not recognised it yet. Trump and his supporters are actively involved in a take over by force.
