I suspect there has been widespread bribing of euro politicians by Saudi Arabia or Qatar. It is far easier and cheaper to fulfill their islamic duties of invasion and conquest by stealth than through outright aggression.
I know this sounds like conspiracy theory 101, but you have to ask why have Saudi Arabia and the other rich Gulf states not accepted any refugees at all? And why have euro pols like Merkel continued to push an obviously crazy and disastrous policy?
We know our own leaders in both parties have been corrupted by middle east money. The Saudi's virtually dictated policy to Bush. They own the Clintons through massive donations to the Clinton slush fund and speakers fees. Obama sat by and let the Saudis destroy the US shale oil industry at the cost of tens of thousands of jobs. These are countries that loll around behind a US security shield and rip us off through OPEC, yet our leaders not only allow it but slavishly cater to them. You have to ask why, not that our media every will.
