Jamal Khashoggi, the Saudi journalist who was brutally murdered in Istanbul earlier this month, was not fond of Israel, to say the least.

“The Jews are without history in Palestine. Therefore, they invented the Wailing Wall, which is a Mamluk structure,” he tweeted in 2015.

Khashoggi also opposed Saudi Arabia’s covert cooperation with Israel, arguing that Riyadh did not need it and that any ties with the Jewish state would unnecessarily tarnish his country’s reputation in the wider Arab world, according to Professor Joshua Teitelbaum, an expert on Saudi Arabia at Bar-Ilan University who knew Khashoggi well.

“He wasn’t a friend of Israel, but he had no problems meeting with and speaking to Israelis,” recalled Teitelbaum, who last saw the slain writer last year, when they had coffee on the sidelines of a conference on the Middle East in Washington.

In one of his last public appearances, Khashoggi, who had ties with the Muslim Brotherhood, confirmed that Riyadh had grown closer to Jerusalem. But he added that the kingdom had “backtracked on some of the more recent pro-Israeli positions it has taken,” according to Middle East Monitor, which hosted him at a conference in London less than a week before he entered the Saudi consulate in Istanbul where he met his death.

Khashoggi’s cruel murder, and the regime’s amateurish attempts to cover it up, have caused immeasurable damage to the international prestige of Saudi Arabia and its de facto ruler Crown Prince Mohammed bin Salman.

The fact that the US and other Western countries are considering punishing Riyadh — Germany has already frozen scheduled deliveries of arms to the kingdom — casts a deep shadow not only over Israel’s clandestine relationship with the kingdom but also over international efforts to keep Iran in check.

For one thing, American and Israeli leaders hoped that MBS — as the crown prince is known — and his ostensible pro-Israel disposition could help force the Palestinians into concessions necessary for peace.

Furthermore, the erosion of Riyadh’s international standing may negatively affect its role as one of the main regional powers standing up to Iran’s quest for nuclear weapons and other belligerent behavior. Mutual enmity toward Tehran, it is worth noting, brought Israel and Saudi Arabia closer in the first place.

“Israel is in a very difficult situation,” said Dan Shapiro, a former US ambassador to Israel. “It wants and needs Saudi Arabia to be a reliable anchor of this regional coalition to confront Iranian aggression, and it’s faced with a reality that the current Saudi leadership has been proven unable to fulfill that role.”

No other Arab country could replace Saudi Arabia in the region’s anti-Iran coalition, but MBS has proven to be “extremely reckless, impulsive and untrustworthy,” added Shapiro, who today is a fellow at the Institute for National Security in Tel Aviv.

Khashoggi’s gruesome murder and the ongoing lies about it are only the last in series of bad decisions made by the crown prince, Shapiro said, which include bombing Yemen without concern for civilian casualties, imposing a siege on Qatar, detaining Lebanese prime minister Saad Hariri, picking a fight with Canada over a Tweet about human rights, and rounding up dissidents.

MBS “frequently acts on limited knowledge and poor judgment,” and the various scandals he has dragged his country into weaken the kingdom and undermine its relationship with its allies, Shapiro charged.

The US should not sever its relationship with the kingdom, as it plays a vital role in America’s efforts to rein in Iran, he said. However, “until there is a change of Saudi leadership, or at least a change in the style of Saudi leadership, the country’s ability to play that role is significantly weakened.”

It remains to be seen how US President Donald Trump reacts as more and more details about Khashoggi’s killing come to light, though he seems determined not let the affair get in the way of what he said was $450 billion worth of Saudi investments. “But we’re going to get to the bottom of it,” he vowed Monday.

Israel’s knowledge of the Middle East is highly respected in large parts of the world, and therefore Israeli warnings of the impact of moving away from Saudi Arabia are very important

For Israel, the situation is somewhat trickier. On the one hand, it does not want to see Riyadh’s position in the region diminished in favor of Tehran, or Ankara. (Turkish President Recep Tayyip Erdogan is believed by some to be seeing the Khashoggi murder as an opportunity to replace Saudi Arabia as the leader of the Sunni Islamic world.)

On the other hand, Israel should be careful not be regarded as Riyadh’s mouthpiece in the US and Europe, several analysts interviewed for this article warned.

“It would have significant negative reputational impact on Israel to be seen as the defender and as the explainer and as the advocate on of MBS after this brutal performance, which was followed by several weeks of lying — which actually still continues — about what happened in Istanbul,” Shapiro said.

Rather, all that’s left for Jerusalem to do is quiet diplomacy in a bid to try sustain “whatever can be sustained” regarding security cooperation with Saudi Arabia, he added.

But there can be no doubt that the Khashoggi affair “has weakened a central pillar of Israel’s strategic concept in the Middle East in a way that Israel can’t do very much to repair it. That’s the damage in having such an unreliable Saudi leadership as we currently unfortunately have.”

Israeli officials have so far not commented publicly on the matter, but they are likely concerned about the possible decline of Saudi’s leadership role in the region.

MBS is leading his country to “the right place,” former national security adviser Brig. Gen. (res.) Yaakov Nagel gushed last year, and that was even before the crown prince surprisingly acknowledged, in an interview in April, that “Israelis have the right to have their own land.”

“Israel’s knowledge of the Middle East is highly respected in large parts of the world, including in Europe, and therefore Israeli warnings of the impact of moving away from Saudi Arabia are very important,” said Dore Gold, a former director-general of Israel’s Foreign Ministry. However, such warnings should take place behind the scenes and not in public, he cautioned.

While Israel waits to see how, if at all, the world will punish Saudi Arabia for killing Khashoggi, it must not forget that Iran’s regional aggression continues without let, stressed Gold, who in 2004 published a book about Riyadh’s support of terrorism entitled “Kingdom’s Hatred.”

“International developments of this sort have their own momentum and can shift the direction of policies in unwanted ways,” he said. “And therefore Israel has to have its eye on the ball, and that’s the Iranian threat, and it has to remind its international partners that this threat has not abated.”
