Harvard Law professor Alan Dershowitz is not happy with Barack Obama.

Dershowitz has been reliably left-leaning on most issues (and as expected from most Ivy League college staff), but he’s also pulled a few surprises out of his hat (like when he slammed prosecutors in Travis County, Texas for pushing forward with a bogus indictment on abuse of power charges against former Governor Rick Perry several years ago (calling it reminiscent of how political dissent was handled in Soviet Russia).

He’s done it again, and he’s absolutely right. Appearing on Monday morning’s “Fox and Friends,” Dershowitz blasted President Obama over his treachery against Israel last week.

“[History will see President Obama] as one of the worst foreign policy presidents ever,” Dershowitz said.

“He called me into the Oval Office before the inauguration — he said he wanted my support, and he told me he would always have Israel’s back,” Dershowitz said. “I didn’t realize what he meant: That he would have Israel’s back so he could stab them in the back.”

He continued: “What he did was so nasty, he pulled a bait and switch. He told the American public this is all about the settlements deep in the West Bank. And yet, he allowed he representative to the U.N. to abstain –which is really a vote for– a resolution that says the Jews can’t pray at the Western Wall, Jews can’t live in the Jewish Quarter [of Jerusalem] where they have 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.”

He also said: “This will make peace much more difficult to achieve because the Palestinians will now say ‘we can get a state through the UN’.”

And there is wisdom in those words.

This isn’t the first time the U.N. have revealed their anti-Semitic/pro-terrorists hand. It’s just the first time a U.S. president has so blatantly been a part of the betrayal. Nobody who has been watching Obama’s actions over the last eight years is totally surprised, however.

Just really, really disgusted.
