How are the proposed agreements with other Arab nations going? Originally that was why Hamas attacked. Did they derail it? If so, they won.

They are all in abeyance.

The war paused all movement on that front. But those proposed agreements didn't arise in a vacuum, so none of them are - or can be - permanently derailed as long as the conditions that prompted them remain. The Arab nations want them in order to provide a regional check against Iranian hegemony. The U.S. wants them for the same reason. Israel wants them in order to provide greater security and increased economic opportunity. None of those underlying factors has changed with the current war. The parties all still want them to happen. The Arab nations don't want to face their various Streets while the Gaza war is ongoing, but they still want the deal.

So while progress has been stopped for now, neither have conditions changed to where the agreements won't go forward.
