Israelis and Palestinians are preparing for a showdown at the United Nations in September, when the Palestinian leadership will ask for recognition of a Palestinian state within the borders that existed before the Six Day War in 1967 (when Israel seized control of Jordanian-occupied territory).

The details of the bid remain unclear, and the effort entails serious risks. But a sober assessment of what might follow a U.N. endorsement of Palestine's borders allows for some cautious optimism.

Given the lasting stalemate in bilateral negotiations with Israel, a Palestinian focus on a nonmember state bid at the U.N. General Assembly might very well increase the likelihood of jump-starting the process. The Palestinian plan already has resulted in an unprecedented diplomatic frenzy.
