Doug, Muslim and Christian "end time prophecies & scenarios" are irrelevant to Judaism and, thus, to Jews, and we don't get worked up over them.  Judaism and the Hebrew Bible existed before Christianity & the GT and Islam & the Qur'an.  In fact, the religions that followed Judaism and survived made up their own "end time prophecies & scenarios" to suit their respective theologies, and they're all inconsistent with what the Hebrew Bible teaches.

Our raison d'être:

WHOSOEVER DESTROYS A SINGLE SOUL OF ISRAEL, SCRIPTURE IMPUTES [GUILT] TO HIM AS THOUGH HE HAD DESTROYED A COMPLETE WORLD; AND WHOSOEVER PRESERVES A SINGLE SOUL OF ISRAEL, SCRIPTURE ASCRIBES [MERIT] TO HIM AS THOUGH HE HAD PRESERVED A COMPLETE WORLD. (Babylonian Talmud, Tractate Sanhedrin, 37a)

The fruits of our effort:

The battle against spiritual terrorism is being won, one soul at a time!!!
