The Japanese fanatics infested every inch of the pacific and the Japanese islands. You have to go to the Islamic world and utterly break their hearts.
It can be done. But they correctly perceive that we do not have the will.
My point is that using nukes to combat Islamic terrorism is a fail. Muslims are everywhere in the world, and it won't stop them. Personally, I think the solution is to expose their religion for what it is, a culture of death. Then we take out their places of worship in the Middle East. Start with Mecca, and lesser places of worship. Do it with non-nuclear tactics, using our military and those of our allies. Break the radical leaders ability to lead. Ramp it up. Once we do that, the moderate muslims will step in and rein in the radicals. Of course, we have to remove Obama and his cohorts first in order to have the will to win. Plus getting our "leaders" to acknowledge that Islamic terror is a problem. A daunting task at the moment. Taking out Teheran with a nuke won't help. Taking out their religious underpinnings will.
