Why they attack
Two major causes of terrorist attacks are religious and political reasons. For example, OBL's 9/11 attacks were motivated by revenge (we killed his children in war), the stealing of their oil, and felt that him and his muslim brother were being unfairly treated, and something has to be done about it.
