Is this the Arab-Spring ripple effect or should I say, aftermath?
This is a good Humanitarianism move, it eventually will boil down to education, job, welfare however, the government needs to be prepared.
Due to the huge inequality of birth rate among different races/religions, I foresee gradually the Arabic population will take over Europe, over probably one or two hundred years that is. Similar thing will happen in USA, with the Latino will become majority, over time that is.
It's all math and physics, the entropy and chaos theory, it's nature force.
