Nothing to do with being inherently violent, or the wrong sort of victims.
@mollyfolk suggested that the Palestinians didn't get as much "support of the international community" as Japan did after WW2, which is clearly nonsense.
Japan had to make some pretty painful concessions after they surrendered. They had to give up territory, make government reforms, disarm, permit occupation, open the country to trade. Their alternative choice was to not surrender, in which case the Allies may have bombed them again. They chose to surrender, with all the concessions demanded. And so they were able to rebuild.
The Palestinians also make choices. But they can only choose from certain possibilities, just as Japan had to. 20 years ago, the Palestinians seemed to have a 2SS as an option. That option required some big concessions which they didn't want to make, especially around the right to return. They didn't choose to make those concessions.
The Palestinians still have agency, both as individuals and as a group, but 20 years of violence later and especially after October 7th, things have moved on. I can't see how Israel would accept a 2SS any more - so that isn't an option open to the Palestinians now - certainly not in the form suggested 20 years ago.
Trump has made a suggestion, although pretty light on details (such as whether it would be voluntary/mandatory, temporary/permanent). There's a lot of noise about it, which was probably his intention. It will be interesting to see what suggestions come out of all that noise.
