@Duncan @cstross De-escalation is quite a tricky thing. And it is important to know what the options of each player are. We are not far enough down the spiral, that the beginning doesn't matter anymore (in which case only victory for one side or war fatigue on both sides, are the only options anyway).
@AndiPopp @Duncan For some insight into de-escalation in this sitch, consider the USA's post-9/11 psychotic break, which lasted about 5 years; by 2011 sanity had more or less resumed. October 6th was an order of magnitude higher per-capita death toll than 9/11 …
I'm pretty sure Hamas weren't aiming that high, any more than Mohammed Atta seriously expected to drop the twin towers. They achieved overkill, again probably by an order of magnitude.
So the current crisis was unplanned.
