Mainstream Islamic organizations 'share al-Qaeda ideology'.
Islam wants the end of the the West, in particular Christianity (the Jews are also included; but they are small and Islam's heroes showed that you can kill a third of all Jews in just a couple of years). Islam is clear in that there is no room in there theology for alternative religions. The sad part about America's activity is that they really believe that all "ideas" can be "liberally" treated. It is a fact that some ideas as just mutually exclusive and cannot be accommodated. Islam is one such idea.
