So says Israeli academic Gadi Taub at Dissent magazine
His reasoning?

But what is worse is that eventually this encroachment on the future Palestine will not achieve Netanyahu’s goals—it will achieve the goal of religious settlers. If they have their way, their asphalt and concrete will prevent partition into two states and will drown the ship of Zionism in a Lebanon-like bi-national swamp. Religious settlers are therefore not just a clear and present danger to peace, or to peace talks, but an existential threat to Zionism itself. Supporting settlement is an anti-Zionist stance. The grounds for resisting the settlers’ enterprise are not only the right of Palestinians to self-determination but also the right of Jews to self-determination. Zionists and their allies must therefore oppose further settlement, for Israel’s, not just Palestine’s, sake.
