Actually, a similar policy referred to as Mutual Assured Destruction (MAD) was one of the keystones in our standoff with the Soviet Union during a little brush-up we like to call the Cold War.
How soon we forget.
The only problem is, the Soviets loved their children. A lot of Islamics will sacrifice their children (and everything else), just to kill infidels. As time goes on, I am starting to believe this madness called a religion will have to be wiped from the earth. The method is presently up for discussion, but I think we're beyond the debate, whether we realize it or not.
