your idea of "forcing" nations to accept foreigners is no different from the genocidal left

It is different, because it means many other countries would now have to deal with this problem as well. Granted, I think it can't be forced. I was just thinking of one potential, peaceful solution, but it would require these countries to do it voluntarily. So China, Russia, Saudi Arabia would implement policies to allow and welcome foreigners, just like it's done in the West.

Of course, won't hold my breath on this one, but I also think war will only make things worse, because of technological advancements in warfare, which would destroy life as we know it. In other words, it might as well be the end of the world, black pill scenario, which isn't really solving anything.
