From the beginning their intent was overthrow of the Saudi monarchy. And the installation of a Islamic state in Pakistan.
They have plans in the eastern part of Africa as well. Most of all Nigeria. So they get control of both Nigerian and Saudi oil/money, and, the military powers of Pakistan. Most of all their nuclear triad of forces.
Sounds stupid now? We may look at things 10 years from now but they are looking 20,30, or more years into the future. Its at that time they want a Islamic super-state in the region otw to establishing one worldwide. Thats why George Bush is attempting to counter with the spread of Democracy and human rights in the region.
Its a mistake to underestimate these people.
