Islam's consistent hostility to infidels.

And, so, now just stick our head back in the sand?

They have wherever they could, whenever the wherewithal presented itself and the enemy was sufficiently weak, acted upon those [Muslim] beliefs. And (what is still more interesting) they have everywhere behaved in remarkably similar ways toward the various non-Muslims conquered and subjugated, whether they were Christians in Arabia or Syria or Mesopotamia or Egypt or Tripolitania, or Jews in Israel and Mesopotamia or Arabia, or Zoroastrians in Sassanian Persia, or Hindus and Jains in Hindustan and the East Indies, or Buddhists in Central Asia, in India, in the East Indies. Everywhere the treatment has been remarkably similar, or perhaps not remarkably, because the texts, the tafasir, the understandings have been, when it comes to Jihad and to Infidels, very much the same.
