Europe is in midst of a terrible refugee crisis, mostly from the Middle East. The endemic poverty of the region has much to do with it, but Europe and America too bear some of the blame. Bashar al Assad ruled Syria with relative peace and stability until Western-supported protest movements made it his way. Europe led the way on Libya, stood aside when Mubarak was in the dock in Egypt, and the US nearly went on a bombing campaign against Assad in Syria, and even now supports anti-government rebels (even while we fight the anti-government ISIS fighters).
In all these cases, we have unleashed the unpredictable forces of disorder, the negative consequences of which should have been apparent from the state of Iraq after our intervention. Libya under Khaddafi, Egypt under Mubarak, and Iraq under Saddam would all be better off–both for us and for their own people–than the current anarchy that the West has encouraged and in some cases created in the name of freedom and liberation.
There is something like cause and effect in this world. And here the cause is the West, its leaders, and their infantile pretensions of liberation and democracy. The effect is chaos, terrorism, refugee crises, Islamist democracy, street fighting in Hungary, and dead kids washing up on European beaches.
In any case, societies have a carrying capacity and, now, regardless of the cause, there is no good reason for Europe or America to destroy themselves in the name of humanitarian compassion. Their own societies will be irretrievably damage din the process, and there is no realistic way to undo the continual flow of such refugees due to the endemic problems and huge numbers of disaffected people in other countries. Indeed, simply rewarding those who by hook or by crook manage to get in the gate is the most irrational and unreasonable policy of all, not least because it guarantees more of the same. It is not a realistic policy for Europe or any of the well-governed and stable parts of the world to absorb the victims of instability, because, indeed, they are also frequently its cause.
