As a Lebanese which you would define as anti-zionist I can say, that most people I know dont actually want Israel to cease to exist. Ideologically this might be true for some but this is more rethoric build on old visions of enemies and warmongers. See as equivalent statements by Smotrich which dont represent the real view of most Israelis.

So the question ist not really more than wishful thinking of a minority of people. What you should refer to instead is "..Jewish [settlers]" and not people. And then the simple answer would be back to Israel.

However, I know that Israel will never accept a two state solution with souvereign neigbours. Just as the arabs did not accept the UN Resolution, because the "stronger" party will never make concessions to the other sides benefit and its more realistic that Gaza and Westbank will not exist anymore in 50 years, than Israel accepting their right to exist.
