If your fundamental goals are dead people and just publicity, sure, then I guess this was a roaring success. Typically success for matters is defined by advancing, say, the freedom and dignity of the Palestinians suffering under oppression, though. And by that very reasonable metric, no, this whole thing has been a catastrophic failure on the part of Hamas, the group that (violently) usurped governance of Gaza years ago. There is unlikely, and this was predictable from the get-go, to be any substantive advancement of the benefit of the Palestinian people, or Gazans in particular. A random lemmy poster put it on a perfectly succinct and correct manner when reports of 10/7 first came out–Hamas shot every single Palestinian in both Gaza and the West Bank square in the dick this time.
