Why lessons learned on October 7 keep IDF in Syria

What Happened

Following the 7 October 2023 Hamas attack, Israel's security doctrine shifted to prioritise physical buffer zones over deterrence and barriers. The IDF entered southern Syria in December 2024, destroying Assad-regime military assets and carving out a roughly 350 sq.km buffer zone, including Mount Hermon, to prevent hostile forces from massing near the Golan Heights. US President Donald Trump, during a phone call with Prime Minister Benjamin Netanyahu last week, reportedly urged Israel to begin withdrawing from southern Syria, seeing the presence as undermining Syrian President Ahmed al-Sharaa's ability to stabilise the country. Israel views withdrawal as contingent on long-term behavioural proof from Damascus, citing the October 7 trauma and concerns that Turkish-backed groups could fill any vacuum.

Why It Matters

The US–Israel disagreement over the Syrian buffer zone reflects diverging lessons from the post-October 7 Middle East. While Washington bets that empowering a new Syrian government can bring stability, Israel's security calculus now demands physical depth against any future cross-border assault—a doctrine also applied in Gaza and southern Lebanon. The stand-off could strain bilateral ties, shape the viability of al-Sharaa's rule, and determine whether Turkish influence supplants Iran's near the Golan, with implications for the broader regional order.

Watch For

Concrete next steps include any formal Israeli response to Trump's withdrawal request, possible US diplomatic or economic incentives linked to a pullback, al-Sharaa's first substantial moves to assert control along the Golan border, and indicators of Turkish or Iranian-backed militia activity in the vacuum. Watch for follow-up Trump–Netanyahu conversations and statements from the Israeli security cabinet on conditions or timelines for redeployment.
