Over at the Lawfare Blog, Elena Chachko has a good rundown of the legal (not political) ramifications of the just-passed UN Security Resolution on Israeli settlements. Chachko, a former clerk for Chief Justice Grunis on the Israeli Supreme Court, contends that the resolution carries few, but not no, major legal consequences. For the most part, it does not alter but does "revitalize" (to use Chachko's term) the international legal case against the settlements.
It's not a long piece, but I'd nonetheless recommend reading the whole thing to get a complete picture that cuts through a lot of the political sturm und drang. And if this does not exhaust your thirst for international legal analysis related to the settlements, you might enjoy this exchange between Eugene Kontorovich and Yael Ronen and Yuval Shany on the international legal validity of Israel's proposed "settlement regulation" bill, which would authorize the (compensated) expropriation of Palestinian land in order to retroactively legalize thousands of unauthorized settlement homes in the West Bank.
