Outgoing US President Barack Obama will be remembered in history as “one of the worst foreign policy presidents ever,” an internationally renowned American legal expert told Fox News on Monday.

“It’s the most undemocratic thing a president can do — to tie the hands of his successor during the lame-duck period,” Professor Alan Dershowitz — a Democrat — said on Obama’s decision to abstain from a vote last Friday on an anti-Israeli settlement UN Security Council resolution that passed by a 14-0 margin.

Before the 2012 presidential election, Dershowitz recalled, Obama “called me into the Oval Office before the election and said to me, ‘Alan, I want your support. And I have to tell you, I will always have Israel’s back.’ I didn’t realize that what he meant was that he’d…stab them in the back.”

“What he did was so nasty,” Dershowitz went on to say. “He pulled a bait-and-switch. He said to the American public, ‘Oh, this is all about the settlements deep in the West Bank,’ and yet he allowed his representative to the UN to abstain, which is really [a vote] for a resolution which says that Jews can’t pray at the Western Wall. Jews can’t live in the Jewish Quarter where they’ve lived for thousands of years and he’s going to say, ‘Whoops, I didn’t mean that.’ Well, read the resolution. You’re a lawyer, you went to Harvard Law School.”

In a pre-election op-ed published in The Algemeiner at the start of November, Dershowitz urged Obama to “resist any temptation, during his final weeks in office, to change longstanding American policy: that only direct negotiations between the parties will achieve a lasting [Israeli-Palestinian] peace.”
