Well, since doing business and helping nations develop is considered "intervention" then let's deport every muslim back to a "muslim" country, build a huge wall around the whole rotten mess and let them fester and destroy themselves without any intervention. The Iran-Iraq war is just one example of what will happen behind that wall. 50 years or so should be just about long enough for them to wipe themselves out...then the rest of the can remove the walls, bury the dead and use the now empty lands as the world sees fit...maybe as a museum to the evil of Islam.
I say build a theme park for radical extremist muslims. We could give them Islamo-Disney. Rides like the "Haj-go-round" or "The Jihad", where extremist can slap on an explosive belt and blow themselves up in a simulated Israeli pizza parlor full of children. Add an "Infidel shooting gallery" (like those duck shooting galleries) where the faithful can shhot at little cardboard infidels.
There are endless possibilities in adapting out videogame technologies to suit the Islamofascist.
any other suggestions?
