Yes, with Christian doctrine you get natural and inalienable rights of man. You get Thomas Paines proof of the illigitimacy of monarchies.

You get freedom of speech, freedom of religion and government of, by and for the people. And what do you get with Islam?
From 632-1924 religion WAS USED to give legitimacy to the Prophet Muhammad's political authority..... by whichever successive caliphate could grab hold of it at the time. Some may view it as a misuse of religion, but to a muslim, familiar with the 1292 years of this history of the Islamic empire, thats a hard sell.
If your still with me, about 1926-27 Ibn Saud was having a hell of a time keeping his Ikhwan fighters religious zeal for Islamic conquest in check and began cracking down and exiling many of them who fled to Egypt. 1928 the Muslim Brotherhood is formed with the motto
this same political ideology continues to this day in Al Qaeda. Yes it is political. The politics that is in the doctrine, the doctrine that has given legitimacy to 1292 years of Islamic government. If your still with me maybe you to can understand what is meant when zarqawi refers to the "Zero Hour".
And Zawahiris response-
YES!!! "Islam, can serve as a platform for political action". The same platform since 632 is applied by Al Qaeda today. Its a fundamental part of Islamic doctrine.
