This Israeli also fails to understand that just as there are "reform" Jews (who are essentially, "non-Jewish Jews," so too many of the Americanized Muslims are not "devout" in the same way that the fanatical Islamicists are.
Now, we can debate which variant of Islam is the "true" Islam---just as people debate which variant of Judaism is the "true" strain---but the fact is, the Muslim Americans here (with the exception of the kook few, as in ANY group) are no different than the Irish Americans who did not support Sein Fein, or the Italian Americans who were not "deep" into the Mob.
He IS right, however, that Israel was founded on a set of RELIGIOUS principles, and abandoned those long ago. Nevertheless, the Lord said there will be a remnant, and He will see them through til the end. So I don't worry about them.
