Others here have asked. Abbas said previously that any Jews that remained would receive the same right as Arabs did in Israel - which rather suggests that there is not an objection in PRINCIPLE to Jewish settlements remaining. There are two obvious hurdles. One is settlement size. A Jewish-only settlement would have to be large enough to support its own services - a senior school, a hospital, a panoply of administrative services, etc., because the Israeli civil administration won't be there to do it. That means settlements of 5,000 or more people. This is underlined by the security issue - the Pal security forces cannot be expected to run 24/7 security on 100+ settlements, not without thousands more gendarmes. The other issue is that many of the smaller settlements are too lawless, whether because they acquired land by keeping the rightful owners off it for 7 years or because they beat up on the locals and the olive trees. No government would thank Israel for that legacy.
