Does history teach us that they were they satisfied with that? No.
Does history teach us that they were they satisfied Gaza was Arab land? No.
Does history teach us that they were they satisfied when the West Banks was Arab land? No.
So what evidence or logic can you use to convince anyone that they will be satisfied with Gaza as a homeland?
As to the idea of settlers antagonizing Palestinians, Gaza has had less conflict that the West Bank or even Israel proper so that argument doesn't fly at all.
It doesn’t matter if there is less conflict in the Gaza Strip. So long as there is conflict, Israel is wasting resources defending these settlements, when they could be defending less contentious parts of Israel.
Agreed that the Palestinians haven’t shown much inclination to be happy with what they did have, but believe or not some Arab countries do now at least recognise Israel, and if the Palestinians get something workable increasing numbers of them might too. I realise that is a ‘might’, but as I say, if the pullout does not happen there will never be peace; that is a certainty.
