What Does Assad's Fall Mean for Israel?

Key Findings:

The collapse of Bashar al-Assad’s regime marks a transformative moment in the Syrian civil war and introduces a new set of challenges and opportunities for Israel. On one hand, Assad’s downfall disrupts Iran’s regional influence by severing a key link in the Iran-Hezbollah land bridge. For years, Syria under Assad served as a conduit for Iranian arms and personnel to Hezbollah, enabling a sustained threat to Israeli security. With Assad gone, Iran’s foothold in Syria is weakened, and Hezbollah, already battered after its two-month war with Israel, finds itself further isolated. These developments are significant wins for Israel, removing a critical adversary who had made Syria a platform for Iran’s regional ambitions.

Despite these gains, the emergence of a new Syria under the control of Hayat Tahrir al-Sham (HTS) introduces new uncertainties. HTS, a Sunni jihadist group with roots in al-Qaida, now leads the alliance of rebel groups that toppled Assad. While the group claims to have moderated its ideology, its history and leadership suggest potential conflicts with Israel, particularly given its leader Abu Mohammad al-Jolani’s apparent interest in reclaiming the Golan Heights. The chaotic aftermath of Assad’s fall also leaves behind significant stockpiles of advanced weapons, including chemical weapons, scattered across the country. Although HTS has vowed to secure these weapons, Israel remains cautious and has already launched strikes to prevent them from falling into the wrong hands.

Compounding these challenges is Turkey’s growing influence in Syria. Turkey backs HTS and has positioned itself as the dominant international player in post-Assad Syria. This shift is troubling for Israel, given the hostile stance of Turkish President Recep Tayyip ErdoÄŸan, who has imposed a trade embargo on Israel and supports Hamas. Ankara’s increasing role in Syria and its intensified campaign against Syrian Kurds complicate Israel’s ability to navigate the region’s shifting dynamics. Syrian instability also threatens neighboring Jordan, a key Israeli ally. Already burdened with economic struggles and a massive refugee population, Jordan faces heightened risks from the potential spread of conflict or Iranian efforts to destabilize the kingdom. As Israel’s longest and least fortified border, Jordan’s security remains a top Israeli priority.

Israel’s immediate focus has been on securing its northern border. The IDF has deployed forces to the U.N.-monitored buffer zone and the strategic Mt. Hermon area, actions it describes as defensive and temporary. These moves aim to prevent the chaos in Syria from spilling into Israeli territory, while the construction of the “New East” barrier enhances border defenses. However, these deployments may face political scrutiny over time, particularly if a new Syrian government emerges and challenges Israel’s presence in the buffer zone.

In the longer term, Israel’s relationships with Kurdish and Druze factions in Syria may play a critical role in shaping regional stability. These groups are natural allies against both jihadist factions and Turkish influence, but overt Israeli support could make them targets of retaliation. Balancing these alliances with broader strategic considerations will be a delicate task. Israel’s overarching goal is to ensure Syria does not become a haven for Iranian forces or extremist groups, while promoting a stable and secure regional order. Achieving this will require a combination of robust border security, diplomatic engagement, and close coordination with international allies to navigate the complexities of a post-Assad Syria.
