I have this idea that I've been thinking about lately. When right wing parties finally get in charge of western Europe, and start expelling the Mohammedian invaders, it's going to be akin to the religious turmoil of the "reformation" that lasted for about 200 years, thereabouts, and involved numerous wars and massacres and particular in Elizabethan England, a level of social control (oaths, fines, etc.) that made the Global War on Terror seem like a school yard play.
There has been a failure to replace the populations...the elite who planned the replacement will shift 180 and go all in on the social control necessary to track down and expel the invaders.
This is a win/lose scenario.
And no, Europe won't go the way of South Africa or Rhodesia. White people there were 5% of the populace in Rhodesia and 8% in South Africa. Such minority status doesn't exist in mainland Europe.
Populism often turn out as a disaster. I even think that it is intentionally implemented in a way to do a maximum harm (if implemented at all) as a kind of punishment for population for their sincere and fair desires.
The clear example of such punishing behaviour was in Argentina, when beloved populist Miley promised to cut government spending. Eventually the major cut of government spending was teachers, medics and state infrastructure workers, and of course not his own cabinet or "important" (absolutely not) departments.
Or take a look as Trump who just didn't fulfill any of his promises.
Looking at all that AfD, LePen and other "right wing" political entities, I don't see anything really thorougly calculated. They talk about what they will do, but never tell how exactly they will fulfill their promises. And migrant problem is just a tip of iceberg.
It's not populism.
It didn't work, they switch gears, expel the Mohmeddians, and in doing so, in all the turmoil, get great control, which is something they want.
Win/lose scenario.
