As I said, the scale of the illegal/undesirable immigration problem in the west is such that it's closer to war than a pure policing operation. Tens of millions of people have been allowed in who need to be deported.

Hmm. Yes. But flooding a country with foreigners, in order to undermine the native population, is a form of asymmetric warfare waged by the government upon the citizenry. I suspect many Americans consider themselves to be in a civil war, and the mass migration is part of that. That means the migrants are part of a military conflict and fair game.

Hell, in a different context flooding countries with foreigners would (quite rightfully) be considered a form of genocide. It's well accepted in international law that trying to dilute a native population out of existence via immigration is genocide. Tibet (Han migration) and occupied Ukraine (Russians) both being recent examples. There are certainly people in western countries whose hatred of white people is sufficiently nutty they their goal with unrestricted immigration is to genocide the white population out of existence (also, Jewish and Asian populations in some cases).

Still, this is not war. You cant just make up a war on your mind to justify your actions.

But you know that this is mostly pure populism. Almost no good numbers to show a real problem. There is more problems within your mind, then there is problems caused by migration. Its called populism. Only because many people say migration is problematic, does not actually make it problematic.
