This is such a complicated idea, and I find myself on both sides and none whenever I think about it. The Us and Them side is biological and fundamental, but the global consciousness side is what I believe the hope of our species to be. I wish all humans could treat each other the same way and collaborate and so on but we aren't wired that way, probably never will be; and there's an argument to be made that even if we were, the necessary homogenization would be worse than the benefits. So do I, and so, I think, does the author of this piece. He's trying to make a sort of utilitarian argument -- what does he say in the last paragraph about shifting probabilities -- which implies a line. The line is different for everyone. Right now it's Netanyahu's line that matters -- or is it Ya'alon's? Or the Israeli voting mass's? The Jerusalem Post did a poll; looks like your average Jew wants to stick it to Gaza. No one is surprised, but you're damn straight Netanyahu had to incorporate that into his decisions on Sunday.I do condemn them for slaughtering other humans. There's a line somewhere.
