In 1683 a massive army of the Ottoman Empire laid siege to the Christian city of Vienna. After two months, an allied force that consisted of men from all over the Holy Roman Empire and from other central European states, including Hungary, and that was led by John III Sobieski, the King of Poland and Lithuania, turned the Ottoman soldiers back, preventing the potential Islamization of the continent.

In recent days, Recep Tayyip Erdogan, president of the Ottoman Empire’s successor state, Turkey, has unleashed thousands of Muslims, mostly young males of military age, upon the European Union, today’s not-so-holy but increasingly imperial reincarnation of the Holy Roman Empire. More specifically, Erdogan, in violation of an agreement with the EU that netted him billions, has allowed – and encouraged – these people, who have been routinely described in the Western media as “refugees” and “migrants,” to storm the border separating his country from the EU’s southeasternmost satrapy, Greece. Indeed, he’s lent them active support, providing many of them with free transport to the border, which they’ve attacked with rocks, “makeshift battering rams,” and tear-gas canisters (supplied by Ergodan) while setting fires and shouting “Allahu akbar!” Photos taken at the border underscore just how perverse it is to call these thugs “refugees” or “migrants.”

Seems like old times. What’s different this time around is that whereas seventeenth-century Europeans understood that they were confronting, in the Islamic invaders of their day, an existential threat to their way of life, many of their descendants don’t seem to have a clue about what they’re dealing with. On Tuesday of last week, and again on Saturday, thousands of Germans, rallying in Berlin and other cities, demanded that the “migrants” on the Greek borders be allowed to pour into the continent and to find their way to Germany, if they wish, so that they can help form “a solidarity society” in which there will be “no more suffering.”
