Whether or not one calls them settlers, then, the Israelis living in the West Bank do not pose either a moral or a pragmatic problem. Their communities are natural outcomes of Israel’s control for almost forty years of areas that are integral to its current defensibility and/or historical heritage.
And since the word settler is loaded with negative connotations of “intruder,” it would be best to cease applying it to Israelis who live legitimately in parts of the Land of Israel that are not annexed to the state of Israel, and whose ultimate disposition remains open. And to drop the immoral paradigm of their forced removal.
He should have read this - "Settler? No. Revenant" - first.
