There used to be a slapstick "joke" of sorts in which a parent is depicted as giving a spanking to a young boy while sternly saying "this will teach you that it's wrong to hit your sister!" The idea is that there is a certain irony behind using physical violence as a means to teach the wrongfulness of the use of physical violence. Some parents, especially those who think that spanking is a great way to discipline children, don't think the joke is funny, even though they get the point. My own experience has been that you catch more flies with honey than vinegar, but I've learned that some parents can be extremely sensitive about this topic. Trying to talk to a pro-spanking parent about alternative methods of guidance for children is rather like talking to creationists about evolution, so I've learned to just smile, nod politely, and hope that calmer heads will prevail.
Of course, that never works. When it comes to dogmatically held ideologies there's no such thing as a calm head. Ordinarily I don't go in for Star Trek references, but there was an episode in the original 1960s series that starred Frank Gorshin as an alien named Bele who was all black on one side of his body and all white on the other, and he was relentlessly pursuing another alien across many star systems or whatever, and he tried to enlist the help of Kirk and the Enterprise in his pursuit. When the other alien is found many sparks fly, because these two guys hate each other with a passion. Kirk and the others are mystified by the level of animosity, and they press them to explain themselves, pointing out that they come from a common culture and have much in common and ought to get along better. The two aliens appear equally mystified by this, and the Bele character points out the "huge difference" between them: "Lokai is white on the right side. All his people are white on the right side." And we're all supposed to go "Whoa, that's really deep, man!"
The Israelis and the Palestinians could change their names to the Beleans and the Lokaians and do a remake of that show. The Israelis, angry for some reason about a barrage of thousands of missiles flying into their towns and villages made an incursion into the Gaza strip, killing 130 people, including some children. So a group calling themselves the Galilee Freedom Brigade launched an incursion of their own into a rabbinical seminary in Jerusalem and shot eight people. In the Strip, the reaction to this terrorist attack was celebration in the streets, with the handing out of sweets to the kiddies and prayers of thanksgiving in the local mosques. It's always good to strike a blow for freedom by murdering some seminarians, I guess. Some of the more militant citizens of Gaza said that Israel is just reaping the seeds it has sown, and I suppose that if one of your children had been killed by an Israeli incursion, you might feel the same way; but perhaps you could have avoided the Israeli incursion if you had not been firing rockets at anybody in the first place.
The lex talionis mindset seems firmly in place in the Middle East. Someone strikes at you, and you strike back. Curiously, the reasoning seems to be that it is wrong for the Israelis to kill innocent civilians, and so to punish them for doing something so morally outrageous the response is to strike back at them by--killing civilians? Well, OK, consistency is the hobgoblin of little minds, and there is a new version of the Golden Rule floating about here. Instead of doing unto others as you would have them do unto you, just do unto others as they have already done unto you, provided what they did unto you was morally wrong. If what they did was morally right there's no need to do anything in reply. This way you're absolutely guaranteed to be always doing the wrong thing, but at least there's a small chance that you'll have the last word in the fight, like Bele and Lokai, who return to their home planet only to find that it has been completely destroyed by a race war. You'd think that something like that would help them to bury the hatchet, as it were, and not in each other's heads, but no, like ideologues everywhere the go down to the planet trying to kill each other, and Kirk and the rest fly sadly away in their starship, shaking their heads at the folly of mankind--or, well, whateverkind Bele and Lokai are supposed to be.
It's hard to hold out much hope for peace in the middle east when the people in charge of trying to figure out what to do in response to some perceived wrong are complete morons, and ordinary citizens find that fact something to celebrate in the streets.
