The only way towards de-escalation is coming to the negotiating table with Hamas. Negotiating with Hamas sets a bad precedent and, in the long term, compromise's the entity's ability to keep Palestine down. Their economy is already severely compromised as it is, so I think that going out with some kind of last hurrah and trying to accomplish all their goals at once is probably more appealing than having to back down, recover, and attempt to do it all again a decade from now.
