This thread has turned into a strange sanctuary for arguments based upon crude collectivist premises and massive ignorance. Please please please be more concise with your arguments and stop introducing racisim and false ideas about Islam into these discussions. Believe me, the ideology of Islam is evil enough. We don't need to ADD things to Muslim ideology that are not there to boost our arguments. For example, I have never heard of Muslims saying nice things about Hitler or Stalin and killing non Muslims is certainly not considered a requirement among orthodox Muslims. Now let me try to provide you guys with a more objective view of the overall situation. I have had several Muslim friends over the years, I've known and spoken to Islamic extremists and I have read several books about Islam including their holy texts.
First of all let me say that I DO NOT APPROVE of mainstream orthodox Sunni Islam. I think that its evils are basically equal, and probably a little worse then Christianity. They do not, however believe in any requirement for the murder of non Muslims. Most passages relating to war and murder in the Quran and within the Hadith can clearly be interpreted as being against this type of action. While there are indeed a couple of conflicting passages there is no modern mainstream Muslim scholar who would issue a fatwa in favor of such actions given the clear arguments against them in most of the main Islamic texts.
The world's Islamic terrorists come from two particular minority groups among Muslims. The first group is known as the Wahabbis. This is a sect (and I would call it a cult) that is a break off from orthodox Sunni Islam and has developed only during the last few hundred years among the people who are now in power in Saudi Arabia. When this group of arabs gained independence from Turkey after WWI they became very wealthy due to oil production and large kickbacks to members of its new royal family. The Saudi arabs began funding Wahabist madrasas (religious schools) all over the world -- especially among poor young muslims in places like Pakistan and Afganistan. To make a general comparison -- traditional Sunni Islam has progressed in terms of being somewhat adaptive to changes in the word. Their system of legal judgements (fatwas) has grown to encompass changes that have taken place in the modern world. Wahabism is opposed to anything new, and they see all of these adaptations as evil and have eliminated all of them from their doctrines. They aspire to what they see as the original "golden age" of Islam and tend to be as radical as possible in terms of their religious findings -- they literally want to return to how things were in the year 650 and they want to bring the rest of the world along with them.
Now as I said, the Saudis began spreading this stuff all over the world. Osama Bin Laden, a Saudi Wahabi is the most famous example of a rich, spoiled Saudi heir who decided to use his money to fund Wahabist Jihad activity, first in Afghanistan and then in the creation of the Wahabi terrorist orginization Al Qaeda. Other examples of Wahabi groups are the Taliban -- which was essentially a Saudi funded and Pakistani supported experiment in creating a pure Wahabi state in Afghanistan. In Egypt there is the Muslim Brotherhood and Egyptian Islamic Jihad (now merged with Al Qaeda). Hamas in Palestine is also a group that is funded by wealthy oil rich Wahabis. London is the main hot bed for Wahabi groups in the West and I was not at all surprised that terrorist attacks have taken place there. Most Islamic extremists I have interacted with have been from London. Also take note that most of the 9/11 attackers were Saudi Wahabis. The insurgents fighting the Americans and the Shia'ites in Iraq are primarily Wahabis allied with old Saddam loyalists.
The second group is the Shia. Shia (http://en.wikipedia.org/wiki/Shia) is an entirely different branch of Islam. They are the majority religious groups in both Iran and Iraq. Back in the 1970s Iran underwent a Shia revolution and is now under the full control of a repressive religious government that preaches on an almost a daily basis famous slogans like "Death to America" ,"Death to Israel", "Death to Britain". They are ruled by the Ayatollahs, who are supposed to be direct descendents of Muhammad and have a virtual monopoly on religious judgments and thus all judgments on what takes place in Iran. They allow for the election of a government to appease the general public but they maintain an iron grip over power with a gigantic secret police organization. They are guilty of funding terrorist groups all over the world. The most famous of them is the Hesbollah which is based in southern Lebanon. This is the main Shia'ite organization that fights with Israel. It should be noted that the Shia and the Sunnis (and especially the Wahabbis) dislike each other intensely. Their feud goes back to the very beginning of Islam. "Al Qaeda in Iraq" regularly launches attacks against Shia targets in that country and has killed thousands of them over the last couple of years.
So, as far as I'm concerned there are two key enemies in the war on terror. The first is Saudi Arabia and many of the gulf Arab states -- our supposed allies whose citizens in fact provide the money and the ideology behind most world wide terror and the government of Iran, which represents a fully religious government and is the seat of power for radical Shia'itism. These governments must all be eliminated before we can be free from the threat of radical Islamic terrorism.
While these groups represent a small percentage of Muslims world wide they represent a large portion of its wealth and propaganda power. The average Sunni Muslim despises Wahabis and complains about them as much as they complain about the U.S. or Israel but they have yet to make clear united public pronouncements against them and they have clearly bought into much of their propaganda. One of the difficulties is, unlike the Shia, there is no central religious leadership among orthodox Sunni Muslims so it is difficult to get them to unite on ANYTHING. Until orthodox Sunni Islam, in a united front denounces and clearly separates themselves from the Wahabis they are in my opinion sanctioning their acts. And unless this suddenly happens it will be up to the U.S. and the U.K. (and hopefully others) to take care of these problems for them and this involves the destruction of the governments of Saudi Arabia and Iran along with the continued aggressive pursuit of terrorist organizations.
