The case for (another) UNSC res. on Israel-Palestine

From Telhami & Goldstein's WaPo op-ed:

What would such a resolution include? Two states, based on the 1967 borders, with comparable mutually agreed swaps. Israel, as a state of the Jewish people and all its citizens, and Palestine as a state of the Palestinian people and all its citizens. The capital of Israel in West Jerusalem and the capital of Palestine in East Jerusalem. Mutual security arrangements to be negotiated, including possible deployment of international peacekeeping forces. And the Palestinian refugee problem to be resolved in a manner that respects the refugees’ legitimate rights, taking into account previous U.N. resolutions and the principle of the two-state solution outlined above.

I'm not entirely sure what the last sentence means, practically speaking. And hadn't the resolution better also say something about equitable arrangements re natural resources (e.g., water)?
