I am not optimistic for the EU to survive long term.

Yeah, Europe is not gonna be the same soon. First there were countries interfering in the Middle East and Africa when it was none of their business , which after every interference came a new immigrant wave, now there are food shortages which were expected to hit the poorest countries and there will be yet another new wave.

Hard times indeed, but from quite some personal experience (living and working in Europe) and historical based facts, I can tell you Europeans are quite more resilient than you might think... Eastern Europeans are tough as shit, literally you can pull two world wars on then back to back and there they are, a walk in the park for them... so okay, maybe not a walk in the park what will happen next, but I bet that's certainly not the end of those guys as we know them. That's my very personal opinion based on my stand of point...

This whole immigrant waves are going to change europe bs is retarded. The european countrys couldn´t be more different and they even have the EU. They fought thousends of wars against each other. As if a couple million foreigners would bring much change...

There isn't any issue with millions of immigrants. The issue is that a lot of them bring their antisemitism and mysogny under the cloak of islam. I know a lot of people who don't pay taxes and when something like the IRS comes around they just collect unemployment money and fuck off to their respective home countries.
Most of the middle east have sent their dumb people to Europe since they get taken care off.
If they get criminal, and get deported they just come back again over and over again.

I would really hope that Europe makes it easier for people to immigrate when they are smart and can take secularism.
