Damn! I like how you think!
Civilized rules don’t work with barbarians.
As they rise to terrorize the world in many ways, we’d best
accept that.
To me it’s really very simple, you have to pay these bastards in the coin of the realm. Unless you deal with them in terms that are important to them, not you, you run the risk of failing to control them. One of their biggest areas of weakness is a religion that believes what someone does to you here can affect your life in the hereafter.
If you’re going to control them in the end you’ll have to use tactics you couldn’t bring yourself to use at first. The only ones who suffer from this inability to do it right in the first place are the innocents that die while you’re screwing up your political courage to deal with the barbarians.
