The effort of the Crusades was sufficient to stop the advance of Islam, but not sufficient to exhaust it. A few centuries after, the Moslem attacked once more, with modern weapons and in a more indifferent age; and, amid the disputes of diplomatists and the dying debates of the Reformation, he succeeded in sailing up the Danube and nearly becoming a central European Power like Poland or Austria. From this position, after prodigious efforts, he was slowly and painfully dislodged. But Austria, though rescued, was exhausted and reluctant to pursue, and the Turk was left in possession of the countries he had devoured in his advance.
And Vienna is under siege again from Islam with “with modern weapons and in a more indifferent age.” This is of course the history of the relationship of Islam to the West. And the modern weapons today include those “useful idiots” of the media. And how more indifferent can Europe be to the siege?
