I just don't think we've anywhere near got our heads around the inevitable future mass movements of our fellow human beings. At present we seem to be tinkering indecisively around the edges. One thing's for sure. Tens of millions of displaced people living in squalid tent cities will be completely unsustainable. Cameron's diversion of a little bit of our overseas aid budget to keep refugees at bay, and his piffling four thousand refugees per annum, smacks of nothing more than positioning himself for the coming anti-immigration onslaught from the right that is inevitable. We've already had don't-let-the-nasty-foreigners-in Farage scaremongering about IS terrorists embedded among the refugees. As a matter of fact, we've had one such scaremonger posting to that effect on this forum. It's going to be a very different world in a few years' time and we will fail to embrace that at our peril.
