I can see the reasoning though I don't quite agree for two reasons.

1) If the Lancet report is at all accurate that's a lot of deaths for the long-term benefits to make up for.

2) How much more extreme has that made the rest of the middle east? How has it hurt the possibility of peace in Israel.

I was, and still am against the start of the war, though I've been fairly consistent in thinking they should stay since then. (Oddly enough I thought the surge was a good idea when virtually no-one else did, though have since started to think it didn't really do anything now that everyone is moving on board!).
