The problem with the EU model is they don't share a common language or culture like the states does or fly the same flag but do have to live under the rule of Brussels and Merkel as opposed to us living under federal laws and DC.
Diluting the EU with Muslims and the USA with Hispanics is causing all kinds of problems and resentment among the (now) indigenous peoples. From my point of view both the Muslim refugees (rapefugees) and the Hispanic illegals (gang bangers) need to go home or just leave the EU and the USA and go to either a Muslim nation or a Hispanic one. The USA must also learn from the EU debacle and prevent refugees from entering. Help them set up camps in their homeland so they can help to rebuild their homes and cities. It's where they belong anyway.
Just a rough sketch of what I see as the key problems with mass migration and the problem with the EU model.
Want proof? Ask the indigenous people of America in the 1600's - 2000's how that mass migration worked out for them and their land.
Except that the left n the US and EU hate western civilization and are doing the illegal immigrant thing to destroy our culture and require an iron fist of government to instill order. Except that I don’t want them to have the iron fist. I want it to bash them into extinction. These elitists are here to destroy us and we need to wake up.
