I've been pondering that for a while--where is it going to start, and how nasty is it going to get. This mass migration at the expense of the native population is of a global nature, and I remember seeing a video of Klaus Schwab stating something to the effect of (paraphrased) "they may end up killing us, but we have to try".
Normally, locking down the lid and plugging the relief on a pressure cooker while turning up the heat is not a good idea, as the PM of Ireland seems to be doing.
