“Might Trump be, in some sense, ‘pro-Israel’? I see no reason to believe that this would be the case,” said Aaron Friedberg, former deputy national security adviser to Vice President Dick Cheney and now a professor of international affairs at Princeton’s Woodrow Wilson School.

“He is unsympathetic to other US allies and generally seems to favor a policy of disengagement from various parts of the world, including the Middle East. He talks tough on terrorism but he has put forward no coherent strategy for opposing it, and his openly expressed hostility to Islam could well make the problem worse.”

Friedberg’s name is among fifty signatures on a letter released earlier this week penned by GOP national security experts announcing their opposition to Trump. The signatories claimed that Trump would be “the most reckless president in American history” should he win in November. The letter also accused the New York businessman of “erratic behavior” that renders him unfit to handle the world’s largest nuclear arsenal.

Indeed, many of Trump’s own party’s top foreign policy figures – who have served in the Reagan, H. W. Bush and W. Bush administrations, and who have throughout their careers worked to bolster the US-Israel relationship – question why he would make an exception of the Jewish state, when the most consistent trait that Trump has espoused on foreign policy is unpredictability.

“Whatever sympathetic noises Trump may currently make about Israel, it’s important to remember that he does not possess clear, steady political convictions – he has changed his views on most issues many times over the past several decades, and even the last few months,” Friedberg added. “Why should he be expected to stand by Israel, or any other US friend for that matter?”

Over the past few weeks, Trump has questioned the purpose of the European Union, the rationale for continuing the North Atlantic Treaty Organization, the worth of free trade across North America and why the US does not more often deploy nuclear weapons.

“There’s no evidence that Trump cares an iota about the Jewish state. He cares only about himself,” said Michael Rubin, a former Pentagon official and a Middle East expert at the American Enterprise Institute. “If he’s willing to throw NATO under the bus, Israelis are foolish if they think he would ever come to Israel’s aid if Israel came under attack.”

Rubin does not believe that Israel will have a friend in the next White House regardless of November’s victor. He questioned Democratic presidential nominee Hillary Clinton’s commitment to any principle over internal party polling, which, according to Rubin, shows a liberal shift on Israel even further to the left.
