The disparate factions of Islam are not fully cooperating. We see small examples of cooperation, but not the nightmare scenario.
If the Muslim factions unite behind a single leader (as Bin Laden hoped), we will face a nightmare war against 1.2 billion people consisting of never-ending terrorist attacks on civilians.
Bush's strategy is to create an offsetting Muslim faction (free and democratic) in the Middle East.
If this happens, there will be NO civilians, only combatants.
I am not convinced that there are 1.2 billion radical Muslims worldwide. Certainly, it is disheartening (to say the least) that very few "moderate" Muslims have been willing to speak up, in fervent opposition to the radicals; and that makes the "moderates" complicit, in my view. But all the Wahhabis (or Salafasts) plus all the radical Shiites would still not equal 1.2 billions Muslims.
Even so, there are more than enough to cause major trouble. And we had better wake up to that fact--soon.
