At which point a bit of history. Fourth century AD and the Goths turned up on the Danube border of the Roman Empire. The usual reason given being that they were being driven west by the expansion of the Huns further east. Lots of argy bargy about whether they should be let in and so on. They and similar confreres (Visigoths, Ostrogoths etc) went on to sack Rome, conquer Spain and Carthage and so on, all that mess of the late empire.
The point being the number of them. At this distance numbers get shouted about but the Goths might have been about 100,000 people. That’s kids an’ all. Roman Empire population was perhaps 50 million.
Which is interesting, isn’t it? Because 2015 saw some 1 million refugees – that’s asylum and economic together – coming into an EU of 500 million or so. 0.2% of population both times.
No, this is not to say that they’re going to sack Rome – not that anyone would notice these days – but it is to say that this is a point of such size that we cannot just ignore it. Something must be done – so, what?
