Syria’s Collapse and Israeli Attacks Leave Iran Exposed

A week of punishing Israeli airstrikes on Syria after the fall of Bashar al-Assad didn’t just set Syria’s own military back years, experts said, but also peeled away another layer of Iranian defenses in the region, leaving Tehran more exposed than it has been in decades.

Iran’s growing vulnerability has generated alarm within the government, stirring fears that its steadily escalating conflict with Israel could soon enter a more dangerous phase. Hard-line supporters of the regime are talking more publicly, and more frequently, about adopting nuclear deterrence to thwart a possible Israeli attack. And among the country’s beleaguered opposition, there is new hope that the crumbling of Iranian power abroad could lead to a loosening of authoritarian rule at home.

“The fingers of the Islamic Republic are being cut off and are getting weaker,” one activist from eastern Iran said by phone, speaking on the condition of anonymity for fear of reprisals.

After Assad’s ouster by Islamist rebels — preceded by the abrupt departure of Iranian advisers and the withdrawal of allied regional forces — Israel took advantage of the power vacuum to destroy vast amounts of Syrian military infrastructure. Hundreds of strikes destroyed warplanes, helicopters, weapons caches and the bulk of the country’s navy.

Israel said it was launching the strikes to prevent advanced military equipment from falling into the hands of militants, but analysts said the attacks were also aimed at further weakening Iran. Under Assad’s decades-long rule, Tehran installed military officials in the country to prop up his regime, and to protect the land routes it used to send weapons and other support to Hezbollah in Lebanon and armed proxies in Iraq.
 
“It was like a root canal,” Yoram Schweitzer, a former Israeli intelligence officer, said of the bombing campaign in Syria. “Iran is always part of the picture.”

Syria’s former radar systems could have provided Iran with early warnings of an Israeli attack, Schweitzer said, while its advanced Russian air defenses were a “constraining factor” for Israel’s maneuverability in the area, according to Gregory Brew, an Iran analyst at the Eurasia Group.

“Israel now has a clear route to Iran and will likely continue to have one for the foreseeable future,” Brew said, explaining that rebuilding or replacing the destroyed equipment could take years.

“Iran was exposed already, and the October strikes proved that,” he added, referring to a wave of Israeli attacks that hit some of the country’s most sensitive military sites. Brew likened Iran’s strategic position to the situation it faced in the 1980s during its brutal cross-border war with Iraq, or in 2003 when the United States invaded Baghdad.

Even before Assad was toppled, Israel was in the midst of an extensive covert aerial campaign against Iranian assets in Syria, carrying out more than 100 airstrikes on Syrian territory since October 2023 — most publicly unacknowledged — according to a U.N. tally.
