I read your post You said the death of that scumbag probably wouldn't have helped. Which I said was nonsense. As you admit when you say it had been planned for a while. Unless they are psychic of course and knew he was going to be offed today. It had no connection, not even probably.
When I mentioned Emwazi (I refuse to call the **** by his nickname) I was referring to the atmosphere around the place more than the actual reasoning behind the attack.
