The fact is, all of the willing Israelites are going to return to Eretz Israel, not just the Jews but many more even. Neither Hamas nor any other Arabs living in this region can do anything to prevent this and violence will be retaliated against... but the Jews and the rest of them are going to have to learn that genocide and ethnic cleansing isn't an option for some of the people living in the Land, and that their own behaviour needs to be modified as well. This is going to take time, but it will happen. Either way, Hamas needs to calm down, submit, and re-evaluate why they (the Palestinians) really want to stay in region and if it's worth it.
