The first thing that needs to be done:
The politicians in each one of the countries that are currently in office and responsible for their insane immigration policies, they need to be brutally and publicly executed one by one. That will put the fear of God into each and everyone of their supporters and constituents- similar to Ceaușescu in Romania whose speech literally pissed off a crowd of thousands so much they no longer gave a fuck and storm his security forces like hankins storming a dojo.
Once their constituents are neutralized the armed forces will follow new leadership. Most of them dont care, they just want to collect their meager pay and shoot whoever they're told to shoot.
Then the clean up begins.
Spain
France
Germany
England
Ireland
Round up those that do not assimilate, those that have already assaulted citizens, stolen without consequences, committed crimes within minutes of setting foot in these new lands, those who came with criminal records and those who've built criminal records since coming over to European countries.
Round them up and drop them off in the middle of Siberia.
Any-counter protesters, blue hair lesbos, f@gs for Palestine, BLM types should be put down with extreme prejudice. Those cowards shouldn't even be extended the grace of a trip to Siberia. They deserve NO MERCY.
