All Islam is radical. It is the antithesis of Western culture. Tell me what exactly you plan to 'stem'. What Bush's advisors think is radical? What Kerry's advisors think is radical? Every administration is going to have a different view of 'radical'. Islam has about one billion 'radical' followers.
It's not a plan to "stem". It's a plan to kill as many as possible in the battlefield that is Iraq.
The more we kill over there, the fewer will come over here.
