It seems to me that the U.S. has its hands full just trying to absorb and take care of the constant flow of "immigrants" flowing across our Southern border from South and Central American nations. This flood of Middle Eastern immigrants trying to enter Europe, is going to create some massive problems....both financial and social...for the European nations, in coming years. There are thousands of Africans flooding into Morocco trying to find their way into Spain.
The U.K, is already feeling some stress from the Muslim influence in recent years....and there are Muslim factions whose primary goal is a complete takeover of the British government.

Germany and Austria, with their open invitation to these Syrian refugees, is going to find that decision coming back to haunt them.
While it is certainly a tragedy to see all these people being displaced...it is just a portent of things to come. This is just the beginning of a massive movement of poor people fleeing corrupt and failed nations, and heading for the more stable countries. As a result, the nations taking these people in will be increasingly unable to support them, and their existing populations will begin to suffer from the decrease in their traditional support programs. As the populations of these disadvantaged people continue to expand substantially, it is going to result in a decrease in the quality of life for everyone.
