What percentage of the world's 1.6 billion Muslim population "is bound by the entire Islamic doctrine?"
About the same ratio as radical Zionists who follow Abraham Kook?
"The earlier influence of fundamentalist Rabbi Abraham Kook (1865-1935), or Kuk, was significant. He preached Jewish supremacy and said: 'The difference between a Jewish soul and souls of non-Jews -- all of them in all different levels -- is greater and deeper than the difference between a human soul and the souls of cattle.'
"His teachings helped create the settler movement, and his son, Rabbi Tzvi Yehuda Kook, founded the extremist Gush Emunim (GE) under the slogan: 'The Land of Israel, for the people of Israel, according to the Torah of Israel.'"

What you're attempting to do here...is downplay the radicalism in Islam. And, you're citing the state-run Egyptian media as an authoritative source on Zionism and Judaism, which is like asking a rabbi his opinion of pork recipes.
The other falsehood that you're is peddling is equating Islamic doctrine with the doctrine of a
single Jewish intellectual. Islamic doctrine comes from Mohammed, the Sunna and the Hadiths, and is not subject to choice. Rabbi Kuk was an obscure rabbi, whose influence was highly limited. A Jew who doesn't follow Kuk's ideology isn't an apostate. A Muslim who denies any of Mohammed's (and therefore Allah's) commands is guilty of apostasy, which is a death sentence. The 1.6 billion Muslims may not all believe as rabidly as the Iranian mullahs, but enough of them do to ensure that the rest fall into line, which is why there has been almost no attempt to reform Islam in the face of modernity. All Muslims are expected to believe that the Qur'an is the word of Allah and has existed eternally, and any deviation from it is apostasy. The schisms in Islam are not doctrinal, but are based on succession and power distribution (Sunni/Shia, Ismaili, etc.), and only occur when someone gets enough power to challenge the status quo. The schisms in Judaism are doctrinal (Orthodox, Conservative and Reform), just as they are in Christianity.
