If you want to understand Israel’s ambivalence about the outcome of Syria’s war, look no further than Avigdor Lieberman. In 2016, Lieberman, Israel’s hawkish defense minister, condemned Bashar al-Assad, the president of Syria, as a “butcher.” He asserted Israel’s moral imperative to oppose genocide, born from the Holocaust, as a reason to oppose the Syrian government’s massacres. It is in Israel’s interest, he added, that Assad and his Iranian allies “be thrown out of Syria.” Fast forward to earlier this month. While touring Israeli air-defense units, Lieberman struck an optimistic note about Assad’s gaining strength, saying it means “there is a real address, someone responsible, and central rule” in Syria. Asked whether he believed this would decrease the possibility of clashes on Israel’s northern border, he said: “I believe so. I think this is also in Assad’s interest.”
Those two positions represent Israel’s conflicted priorities in Syria. On the one hand, Assad is Iran’s most important ally in the Arab world—the state he rules provides Tehran with access to Israel’s northern border, and facilitates the flow of weapons to Hezbollah. On the other hand, Assad—his government’s fiercely anti-Israel rhetoric notwithstanding—represents a known quantity to Israel, unlike the chaotic tangle of Sunni militias and jihadist organizations that would replace him. Until recently, Israel’s border with Syria had been its quietest frontier for four decades. [...]
Israel’s reliance on Russia is a result of President Donald Trump’s hostility to a long-term commitment to Syria. Trump told the military earlier this year to prepare to withdraw all U.S. soldiers from the country, and earlier this month announced that the United States would not spend $230 million that had been earmarked to help rebuild the country’s shattered infrastructure. “If you’re an Israeli policy maker and you’re looking at Syria, you see Russia is there and obviously staying,” Itamar Rabinovich, Israel’s former chief negotiator with Syria in the 1990s, told me. “And you see the United States—the president says one day that he wants to withdraw the 2,000 [American] troops, and the next day he faces some pressure and keeps them there. But is that reliable in the long term? Doubtful.” [...]
As these political and military dramas play out, there is little question about a fundamental fact—Iran and its allies are poised to challenge Israel on multiple fronts in the years ahead. In Lebanon and Syria, Hezbollah boasts more fighters and better weapons than at any point in its history. Earlier this year, in the Gaza Strip, Hamas and Israel engaged in a series of tit-for-tat clashes for months before a cease-fire took hold. And in Iran, there is a growing risk that the Islamic Republic could restart its nuclear program following the Trump administration’s decision to reimpose sanctions on the country.
