Different populists have different ideal numbers for how many people they want to purge. Some want 10 million, some want 20-50 million going decades back and reversing whatever laws allowed the "wrong kind" of even legal immigrants to come here in the first place.

I think more governments around the world are catching on to the idea that your majority population can excuse a large amount of economic mismanagement and bad geopolitical strategy if you blame foreigners who arrived after your decline started.

If a satisfactory amount of foreigners are removed, the technology will still be there and the defense contractors will still need contracts. If there are no viable foreign adversaries at that point, then another domestic target will be needed.
