Most of the attackers completed their studies in Western universities where they for the first time Russian for company got in touch with Al-Qaeda. Terrorists, who were in charge of the London bombing fit to this scheme as well. There were four boys with ages between 19 and 30 who were living in UK, who were studying or working, including one of them, who had pregnant wife. What we can observe from presented information is that the majority of terrorists are either born in Western countries, or immigrate or study there for a significant part of their lives. A lot of them convert to Islam, from being atheists or agnostics. Lots of them became fundamentalists just after converting or realizing the importance of religion. It leads to the thesis that Islam itself in not a cause of terrorism and fundamentalism. As we can see from the example of terrorists who were in charge of the London bombing, two of them were good students, British citizens, and people who were not very interested in religion. However they changed after their trip to Pakistan. We might assume that they were brainwashed over there and it was the cause who they became terrorists and participate in the London bombing. Marc Sageman in his book presents a conversation between two Egyptian Muslims. One of them, Ahmed Al-Sayed Osman Rabei, was implicated in the Madrid bombings, and the other, Mahmud, was his roommate and a nonterrorist. This conversation shows their different perspectives on religion. When Rabei claims that Americans are enemies of God, Mahmud answers: “Listen to me, there is only one God. Frankly, I do not care if someone is Jewish, Orthodox, or Catholic; everyone is free to pray to the God he chooses, and it is neither up to me nor up to you to judge. (…) I only know one thing: praying to God. The important thing is for you to know God, to pray, and not to behave badly, and to not do things that are not right. All the rest is superficial (…)”. In this conversation we find the contrast between two types of Muslims: one type, which followed the Quran and another type, which went through brainwashing processes and became capable of being involved in terrorist attacks.
