When I went to Sri Lanka and travelled to Jaffna, I was amazed at the quality of the roads there. What happened to the Tamil people at the end of the war was barbaric, just like Black July was. Hopefully, with the economic development that has taken place in the North and the East of the Island, civil war will not return. Just like I hope this is the case in Northern Ireland. Basically, people have gained through peace and have too much to lose.
Sadly, this has not been the case for Palestinians. Since the Oslo Accords were signed in 1993, Palestinians have lost land in the West Bank and Settlers attack them with no consequences. Negotiations have failed them. Put simply, the attacks of October the 7th were evil and cannot be defended. But Christians and Muslims living in the West Bank see that settlers can carry out attacks on a smaller scale, and the Settlers who carry out the attacks face no consequences for this.
If Israel wants peace, it either has to engage in ethnic cleansing (again) or it has to make it that Palestinians do not lose out by choosing peace.
