First I must say the meaning of Islam is complete submission to the one true G-d. Also part of the verse they speak before they read in the Quran is "it is you we seek for help", further Israel is considered as "People of the Book".
If Israel is the "People of the Book" then what do arabs have? If the Quran is all they have then many are left to their own devices which we see can have devastating effects...
With such lost souls clinging to what they view as holy they seem to be open targets for recruitment tactics such as "you will recieve 70 virgins when you become a martyr for the jihad".
How unfortunate so many are brainwashed like this... If those celebrations of the WTC/Pentagon bombings, such deep-seated hatred and low veiws of life itself, are any indication... Probably yes this is just the beginning of the attacks... but doubtful if they succeed, yet they shown they are extremely resourceful and there may be plenty of "sleepers" ready to strike when given notice and method of attack.
But come on now can they ever really win? The answer a resounding NO!
