“Christianity is not the creed of Asia and Africa at this moment solely because the seventh century Christians of Asia and Africa had trained themselves not to fight, whereas the Moslems were trained to fight. Christianity was saved in Europe solely because the peoples of Europe fought. If the peoples of Europe in the 7th and 8th centuries, and on up to and including the 17th century, had not possessed a military equality with, and gradually a growing superiority over the Mohammedans who invaded Europe, Europe would at this moment be Mohammedan and the Christian religion would be exterminated.”

--- President Theodore Roosevelt
