Remember Moore's Law, which predicts a doubling of computing power every 18-24 months, or something like that? First postulated in 1965, it's still running strong more than 40 years later, which is why we can have the blogosphere.
Well, since the peak of Palestinian violence in 2002, Israel has cut the number of it's casualties by half, each year. Including 2007, in which 7 Israeli civilians were killed, compared to 17 in 2006. Predictably, the number of dead Palestinians also fell significantly. (These numbers and others can be found in a B'tselem report cited here).
The moral of the story, as I've often told, is that violence is often best answered with superior violence. Especially in the cases where the original violence is fueled by animosities that cannot be made to go away except perhaps through abject surrender to the haters.
