Germany's Angela Merkel opened the floodgates by inviting the 3rd world into the EU. It's the main reason the UK left the EU. After Merkel stepped down as the head of Germany, she admitted it was a failed project.
Most of the EU is extremely far left, so they love and worship the 3rd world illegals. The EU punishes the member states that refuse to allow illegal immigration.
BTW, I'm a dual US/UK citizen and my husband is British. We had to leave the US because his Green Card was delayed because Clinton gave illegals amnesty, and GWB gave the illegals amnesty the right to bring in their families, and gave them priority in the queue. If GWB didn't do that, we'd be in the US still. INS (whatever it was called back then) sent that letter letting us know that his GC would not be processed in time, so he had to leave and not come back for a year. He should have done it illegally and gotten amnesty, and we'd be set.
