A politically powerful segment of Israel is adamantly opposed to the two-state solution. And the strategic positioning of Israeli settlers over the years on WB land (in violation of signed treaties) has intentionally rendered establishing an independent WB as "logistically impossible" due to "security concerns" (protection of the settlers). There's no way forward without removing the settlers, and removing the settlers is political suicide in Israel, where hard-right parties have an oversized influence in the government.
