Here's the bottom line. Until Muslims take account for the Jihadists in their midst, until they stop them, then Muslims are placing themeselves and all of Islam at risk. What do you think will realistically happen if the US is hit by a Nuclear bomb from a Jihadists, or if Israel is? Do you believe Mecca will be spared? Are you willing to chance it? And what do you think the destruction of Mecca would do to Islam?
Meanwhile, there are some who believe that Jihadism is so ingrained in Islam that it cannot be stopped - that Islam and Jihadism are one and the same. It is not the most unreasonable belief, sad to say, given the mass support that OBL and other Jihadists have in the Muslim world - in the way the Muslim world views this as a conflict of civilizations.
If the US had a bunch of ex-green beret's committing acts of terror in the Muslim world - blowing up buses and hotels, etc. - murdering people - what do you think the US would do? Don't you think they US would first renounce these people, turn over everything they have on them, ostracize anyone who supports them, cut off all the finances, and then join in the hunt themselves - so that the US would not be tainted with the evil of these Green Beret's.
but that is NOT how the "Ummah" has reacted - they have reacted with denial and then justifications. That leads to the suspicion that Islamdom in general approves of these attacks on the West.. that they approve of Jihadism. That instead of renouncing, Muslims embrace the Jihadists. But, Bush was right. In this war you are on one side or another. Islam needs to choose. Is it on the side of the Jihadists, or on the side of peaceful co-existance in this current world-order. If Islam, on the whole, is on the side of the Jihadists, then Islamdom must be prepared to bear the consequences of that support.
