The claim that Israel is waging an illegal "war of aggression" against Syria for territorial conquest collapses under the weight of verifiable fact. Israel's military operations in Syrian territory from late 2024 through 2026 were triggered by a specific and unprecedented security emergency: the sudden collapse of the Assad regime in December 2024, the dissolution of Syria's conventional armed forces, and the emergence of a post-Assad power vacuum that left vast quantities of advanced weaponry—precision-guided missiles, anti-aircraft systems, chemical weapons precursors—at risk of seizure by jihadist groups. Far from being "unprovoked," these strikes followed more than a decade of documented Iranian weapons transfers through Syrian territory to Hezbollah, a pattern that Israeli and Western intelligence agencies have consistently identified as an existential threat. To characterize measured, target-specific responses to this cascading threat environment as "aggression" is not analysis—it is propaganda.

The Facts on the Ground

The legal and strategic foundation for Israel's posture in Syria is neither novel nor opaque. For four decades, Israeli-Syrian military relations along the Golan were governed by the 1974 Agreement on Disengagement, brokered by Henry Kissinger, which established the UN Disengagement Observer Force (UNDOF) buffer zone and committed Damascus to preventing terrorist infiltration through its territory. With the fall of Bashar al-Assad, Israel's government took the legally defensible position that the disengagement agreement it signed with the Assad family government was rendered inoperative—at minimum until a stable, accountable Syrian authority could reestablish border security. This is not a pretext; it is a coherent reading of treaty obligations that require a functioning counterparty.

According to analysis by the Washington Institute for Near East Policy, Israel's initial military priorities upon Assad's fall were threefold and each was demonstrably security-driven. First, the IDF launched a comprehensive air campaign to destroy Syria's strategic military arsenal—aircraft, missiles, naval assets, chemical weapons infrastructure—specifically to prevent these capabilities from falling into the hands of jihadist factions. Second, Israel established nine military outposts within the former UNDOF buffer zone to prevent a security vacuum along the Golan frontier during the chaotic transition period. Third, Israel conducted targeted strikes against Turkish-supplied anti-aircraft systems and missile batteries being deployed inside Syria, a direct counter to expanding hostile military infrastructure near its border.

• Israel has not declared any annexation of Syrian territory captured or patrolled in 2025–2026; official Israeli statements consistently describe the presence as temporary and conditional on Syrian stabilization.
• The IDF's destruction of Syrian regime weapons stockpiles was described by independent analysts at the Washington Institute as "justified," preventing those assets from "falling into the hands of jihadists or other nonstate malefactors."
• Israel's operations against Iranian-proxy infrastructure in Syria date to 2013—over a decade of documented strikes targeting IRGC formations, Hezbollah operatives, and precision-missile transfer routes—establishing a clear, consistent, and transparent security rationale that predates any change of Syrian government.
• Israel intervened militarily in summer 2025 to protect the Druze community in Suwayda province from sectarian violence by Sunni militias, a humanitarian intervention with no territorial dimension.
• Article 51 of the UN Charter preserves the inherent right of self-defense against armed attack and against imminent threats; UN authorization is not a prerequisite when a state acts to prevent its territory from being used as a weapons corridor or staging ground by hostile non-state actors.

The "Greater Israel" Allegation: A Recycled Propaganda Template

The "Greater Israel" accusation—the claim that Israel harbors a secret plan to conquer Arab lands "from the Nile to the Euphrates"—is one of the most durable and most thoroughly debunked pieces of anti-Israel propaganda in circulation. It has been repeatedly examined and refuted by scholars at the Jewish Virtual Library, among others, who note that no such map hangs in the Knesset, no such official policy exists, and Israel's actual territorial history runs directly counter to the expansionist narrative. Israel withdrew fully from the Sinai Peninsula in 1982 under the Camp David framework, returning every meter of Egyptian territory despite significant domestic opposition. Israel withdrew from South Lebanon in 2000 and from the Gaza Strip entirely in 2005, dismantling all Israeli settlements there in the process. These are not the actions of a state driven by an insatiable territorial appetite.

Moreover, Israel has historically signaled willingness to negotiate over the Golan Heights itself. During multiple rounds of indirect and direct negotiations with Damascus between the 1990s and 2010s, Israeli governments offered substantial territorial concessions in exchange for a genuine peace treaty and Syria's severing of its relationship with Hezbollah and Iran. It was Damascus—not Jerusalem—that repeatedly refused to formalize peace. The current Syrian transitional authority, led by Ahmed al-Sharaa (a figure with documented ties to al-Qaeda and ISIS), has given Israel no basis for confidence that the post-Assad Syria will honor prior security frameworks or prevent its territory from being used to threaten Israeli civilians. In that context, Israel's forward military posture is a rational precautionary measure, not imperial conquest.

Why This Narrative Is Dangerous and Must Be Rejected

Labeling Israel's documented security operations as a "war of aggression" inverts the moral and legal reality in ways that have direct consequences. It strips Israel of its recognized right under international law to act in self-defense against threats emanating from foreign territory. It obscures the real aggressors in the Syria theater—Iran and its proxy militias, which spent years converting Syrian soil into a forward base for missiles aimed at Israeli cities—and instead redirects international outrage at the party that was targeted. It hands diplomatic cover to the jihadist groups now operating in Syria by framing Israeli countermeasures as the source of regional instability rather than the decades of Iranian subversion that destabilized Syria long before Assad fell.

The claim also serves as a vehicle for mainstreaming the antisemitic "Greater Israel" conspiracy theory, which falsely portrays Jewish statehood itself as inherently predatory and boundlessly ambitious. Responsible analysis must firmly reject this framing. Israel's operations in Syria are strategically debatable in scope and risk calculus—as serious analysts at institutions like the Washington Institute and INSS have openly noted—but they are neither illegal acts of aggression nor evidence of a hidden annexationist program. Conflating legitimate security operations with conspiratorial empire-building is not criticism of Israeli policy; it is the recycling of a propaganda template designed to delegitimize Israel's fundamental right to exist and defend itself.
