Eventually eu will kick usa from nato to get the upper hand and rearm with european made weapons(they are better than usa made ones anyway, shocker) which will prop up the eu economy(no more money for usa military bases around the world). Energy will keep being a problem, eu will not mend ties with russia any time soon. As long as eu exists borders and white replacement will keep being a problem. UK will lose the economic infrastructure of city of london, maybe even get civil war..
@UncleIroh europe is "the old continent" and because of that, there are little resources left. dense infrastructure, but manufacturing is completely dependent on imports of raw materials. by cutting off russia, europe has committed suicide. you are correct, it won't be pretty. i see no way out of the inevitable economic crash of quality of life here. but i think western europe will suffer way more than centra/eastern europe because only west lives above its means.
