There's no much talk of historical claims on Gaza from Israelis besides very fringe groups who don't number a lot of people.
They're certainly quite obnoxious, these groups. But they can't be called "fringe" anymore, now that they've been made coalition partners in the 37th government (receiving very prominent cabinet positions to boot). Meanwhile Israel's expansionist claims on the West Bank have been the de-facto national consensus (and have been supported by every government to one degree or another) since the late 70s.
If there are major historical claims they mostly come from the Palestinian side
These aren't "claims" coming from their side as it has always been their land to begin with.
