The West Bank has nothing to do with the politics of Gaza. They are run by different entities. There are no Jews in Gaza, and the attack on Israel was from Gaza.
The West Bank is a mess, and there should be no settlements there. The right wing has a lot of power in Israel because it is always the party that gives power to the other parties, if you know what I mean.
Netanyahu is supported by the majority in Israel as they all believe (as do I) that Hamas and the Jihadi needs to be wiped out, and without them being wiped out, there will never be peace in the Middle East.
