I am going to say something that will most likely get me banned but what heck I well say anyway.
The best allegory I have heard. You are living in Americas south west where rattlesnakes are a real problem. You are working in your yard, when you see one. You want to protect your children and the neighborhood so you go to kill it. It slithers under your house through a hole in the crawl space. You open the crawl space door and look in with a flashlight and you see the dirt move as the area under your house is full of rattlesnakes. While you are watching, one moves up into the wall of your house. You cannot burn them out without burning your own house down. You cannot smoke them out without causing sever damage to you house, and poison will not insure that you get them all. You go inside you house and notice a snake in the guest bedroom, and one in the toilet area. You know that unless you brother them the snakes will not attack, but they are everywhere in your house and you cannot be sure that you are safe anywhere. In the end, you decide that they only way to remove the snakes is to burn your house down. While your house is burning you see the snakes scatter some to the woods, some to the road where they are quickly killed by cars, and a lot of them going into your neighbor's crawl spaces. You neighbors are now confronted with the same problem. If you rebuild your house, when the neighbors have to burn their homes, you will get infested with the snakes again. It now becomes a never ending battle with the snakes. This is what we face with radical Islam.
So what is the answer? After you burn your house down, you rebuild it in such a way that the snakes cannot find a way back in (Ban Islam. In America this would require a Constitutional Amendment). Then you help your neighbors to rebuild their homes to keep the snakes out (Muslims are not allowed to even visit your country). Evidently they will be confined to the woods, and every so often you and your neighbors will have to mount an assault on the woods to kill as many of them as you can. It is the worst answer I can come up with, but maybe the only solution.
The only answer I can come up with sounds way to much like Nazi Germany. But what is the answer? Not poking around in the snake dens in their land is a good start, but we have nests of them already in our home as well as our neighbor's home. When you back away from the dens in your own home, then you forfeit to the den the freedoms of your own family. In addition, the wild ones in the den will venture out either for food or just to be a general pest. Eventually, you will have to deal with the dens in your own home. There is no good answer that can come from us. The only good answer is for the majority of the Muslims to leave the 7th century and join the rest of the world in the 21st century and in so doing shut down the radicals in their neighborhoods and work to make the world a better place to live. The key question is, how long will it take for that to happen and how many of our family members must die before it happens?
