I feel like the British situation should be a pretty damn good example for other countries like Japan, new Zealand, to listen to and learn from, hopefully preventing the same outcome before it's too late - there is no going back. You can't undo it.
Perhaps the most underappreciated problem in this is the UKs desperate need to feel like it's still a big player, like the big little brother USA somehow gives a shit about what we say and do. We constantly feel responsible for everybody else's suffering, meaning we open the floodgates indefinitely at the expense of people like me and, well, everybody else. It's all so stupid
