Weird imo how the Brits came close to being over-run by Nationalistic Nazis and now it seems to be heading towards Nationalism itself. The same with the USA! Other countries heading that way! The days of countries getting on with one another seem to be over and now its retreat, isolationism, trade barriers, some countries muscling up. We are in a nuclear age now and such division could finally bring the long stretch of relative peace since WW2 crash to an end. Is the day of the apocalypse coming? I hope not for our children's sake and the future of humanity!
