McCain: Israel-U.S. ties never been worse

US Senator John McCain says the ties between the U.S. and Israel have never been worse than under the Obama administration.

Speaking to CNN on Sunday, McCain asserted that Obama “had very unrealistic expectations about the degree of cooperation that he would get from Israel, particularly on the Palestinian issue as well as on the nuclear issue with Iran.”

While the relationship between the U.S. and Israel has not always been excellent, McCain said, "any observer would argue they’ve never been worse.”

He called the deteriorating ties "a tragedy."

McCain's statements were made on the backdrop of a crisis in the U.S.-Israeli relations, sparked by an invitation extended by House Speaker John Boehner to the Israeli Prime Minister Benjamin Netanyahu to address Congress next month on the issue of the nuclear talks with Iran, according to the Qods News Agency.
