For the American Jewish community that voted overwhelmingly not once, but twice for President Barack Obama, the US abstention and refusal to use its veto power on an anti-Israel measure at the UN was a betrayal of historic proportions. For the Jewish alt-left, which includes groups like the New Israel Fund and J Street — supported by mega-donor George Soros — this was a stellar victory. They have clung to the myth that the settlements are obstacles to peace. They seem to have forgotten that Israel gave up Gaza in an anticipated exchange of land for peace, while actually risking civil war and yielding land for rockets, missiles and underground terror attacks.

There were signs of last week’s move by the White House at the Security Council. Obama’s excising of the voice of the Zionist Organization of America from the table of national Jewish advisers and replacing it with J Street was a mile-marker on his road to perdition.

Indeed, many liberal Jews not only fail to understand the significance of Obama’s abstention at the UN, but some naively believe it will move forward the peace process. The absurdity of this position is revealed in the expectation that the Palestinians will now feel compelled to negotiate what the UN has already given them. According to the UN, the Jewish section of eastern Jerusalem is now in Arab territory, as is the Western Wall. Indeed, even bustling portions of the economically thriving parts of main Jerusalem are probably east of the 1967 armistice lines, according to some interpretations.

If anything, the Obama administration has further undermined any reasonable expectation that the Arab-Israeli conflict will be resolved through negotiations. No Palestinian negotiator can demand less than the UN has already given the Palestinians, and no Israeli can give away Israel’s holiest sites or uproot the hundreds of thousands of settlers who dwell east of an armistice line that was never meant or expected to be a border.

The UN resolution’s de facto defining of a Palestinian state on the 1967 armistice line — the Auschwitz border, as Abba Eban so accurately called it — will never be accepted by Israel no matter how such “democratic” states as Russia, China and Venezuela vote.

The Arabs have had ample opportunity, as far back as the last 1930s, to accept a state alongside a Jewish state, and they have always said “no.” The only reason to have a Palestinian state now is to put another Gaza on Israel’s narrow 12-mile border.

Israel will never accept the conditions of suicide Obama has created for it. But, rest assured, Israelis will find in this UN resolution new motivation to continue to expand Israel into the disputed territories.

In the words of Tzipi Hotovely, Israel’s deputy foreign minister, “History shows there are events which create drastic changes in Israel’s response. History will remember the UN Security Council’s Resolution 2334 as the one which brought about Israeli sovereignty in Judea and Samaria. No decision will cause Israel to stop building on its own land.”

Far from burnishing Obama’s legacy, this leaves it in flames.
