OK, once more with feeling. Killing these Muslo-jihadis is like killing cockroaches. The job’s done when the last one is dead.
You can’t bargain with them, and you can’t play “live and let live”. They don’t just hate us, they want us dead. The only way to win is to win so completely that they never want to tangle with us again. And for a group that is still killing each other over things that occurred more than a thousand years ago, that’s going to mean killing them all.
Just like you do when you have cockroaches.
