It is likely that the principal objective of Hamas on October 7 was to disrupt the negotiations between the Israelis and the Saudis. If that is your measuring stick, are they succeeding?
Let’s put it this way: if Israel doesn’t change course, it will face complete diplomatic isolation and lose any hope of a regional alliance with moderate Arab states for the foreseeable future. It will also be on the hook for all of the costs of an expensive occupation that it cannot afford. For all of that, it probably won’t be able to destroy Hamas, because killing lots of people and persuading them of the fallacy of an idea are two different things entirely.
That sounds like a Hamas victory to me.
