[Antidote: Freedom
With these three principles -- moral clarity, strategic clarity and the imperative for victory -- the defeat of terrorism is not as distant as many people think. Beyond that, if I had to point to the one thing that is needed in the Arab and Muslim world to ensure that the next century will be better than the last -- for them and for us -- it would be to promote democracy, a free press, debate and dissent. In the end, the only antidote to terrorism is the antidote to totalitarianism. It is freedom. It is what the American flag represents to me and to billions in the world. It is the key to securing not merely peace of mind, but peace between peoples.]
The very laws of Islam make it impossible to coexist with any other religion, or even any secular way of life.
Shari'a (Islamic law) is why none of the Moslem countries are democratic, because democracy is literally against the Islamic religion. Islam is not a religion, which can be separated from the state; it demands that the state laws be Shari'a laws. Shari'a forbids non-Muslims from having authority over Muslims.
The Shari'a determines Muslim behavior. Therefore a state for Muslims must implement this law. The Shari'a has never been collected and specified in a particular 'law book', the Shari'a is best understood as a shared opinion of the community, based on a literature that is extensive, but not necessarily coherent or authorized by any single body. This means that ultimately it gives totalitaric power to whom ever is ruling.
This in contrast to most current legal systems in the world, where the law is defined as systematic set of paragraphs and sections that is written down in what we call a law code. This code is normally written and authorized by a specific body, elected or otherwise: a legislative assembly. There fore basically everyone is playing by agreed upon and the same rules. Because the Shari'a does not have such a specific form, it is known as an uncodified law.
Turkey is a westernized country, and enforces its laws as such. (The Turks, rather than destroy, absorbed much of the Byzantium culture, much like Rome did after conquering the Greeks.) Turkey is also the regional ally of Israel. It was under the Ottoman rule that the zionist movement started.
In Jordan, there are several court systems. The Muslims, Christians, and Jews all get their own system for intra-religious issues, and then they have a secular court system for inter-religious issues. (Ironically, the King of Jordan claims divine right to the throne as a descendent of Mohammed.)
Also note that Iraq is a secular country. Saddam only cries Jihad! when he thinks it will serve his intrests. Also, the Deputy PM of Iraq is a Christian.
