Novel Idea On Dealing With Terrorists

I heard a veteran talking over the weekend about thinking outside the box in dealing with terrorists. He said that radical Muslims don't care about the same things most others care about. They care only for their Mosque, their family and tribe, their faith. So, he suggested, how about we make it known that if you are found to be a terrorist, (even after you blow yourself up) your entire family will be deported to your country of origin. For home grown types, we take their families off any and all government subsidies. What do you think about this idea?
