Israel’s parliament has approved a measure backed by Prime Minister Benjamin Netanyahu which could require a national referendum on potential land-for-peace deals concluded with Palestinians and Arab neighbors. The Israeli law covers any agreements involving a pullback from occupied land Israel has already annexed—East Jerusalem or the Golan Heights captured from Syria. Critics argued the bill could further complicate U.S.-backed talks with the Palestinians. The chief Palestinian negotiator, Saeb Erekat, denounced the measure as a “mockery of international law.”
