Fermer la brèche orientale : Mettre fin à l'ère de la frontière ouverte dans le Levant post-Assad

[FR] The collapse of the Assad regime has liquidated the strategic "anchor" of the Iranian land bridge.
For the United States, Lebanon’s eastern border is no longer a peripheral concern—it is the
primary fault line in the containment of the IRGC. A sovereign Lebanon requires a hard,
militarized border. Anything less is a direct subsidy to regional instability and the global
narcotics trade.

I. The Death of the "Resistance Highway"
For 40 years, the 230-mile border with Syria was a fiction maintained by the Syrian-Iranian axis.
 The Strategic Vacuum: With Damascus no longer serving as a regional hub for the
IRGC, Hezbollah is scrambling to fortify illicit mountain passes and tunnels.
 U.S. Interest: Permanently severing these logistics routes is the most cost-effective way
to neutralize Hezbollah's military capability without direct U.S. kinetic involvement.
II. The Captagon Corridor: A U.S. National Security Threat
The Lebanese-Syrian border is the world’s primary artery for Captagon, a trade that funds the
"Axis of Resistance" to the tune of $10 billion annually.
 Destabilizing Allies: This narco-economy targets U.S. partners in the Gulf and Jordan,
fueling domestic instability and funding the next generation of proxy militias.
 The "Unit 900" Smuggling Nodes: Hezbollah’s counter-intelligence unit controls the
"illegal crossings" that bypass official customs. These are the same routes used to move
advanced missile components and IRGC personnel.

III. The LAF Mandate: No More "Strategic Ambiguity"
The Lebanese Armed Forces (LAF) have received millions in U.S. Border Security (Section
1226) funding. The 2026 U.S. policy must be binary:
 Physical Control: The LAF must move from "monitoring" to "interdicting." This
includes the destruction of all tunnels and the deployment of U.S.-provided sensors at
every mountain pass.
 Purging Infiltration: U.S. aid must be immediately suspended if pro-Assad or pro-
Hezbollah elements within the LAF continue to provide "safe passage" to militia
convoys.
IV. Policy Mandate for U.S. Decision-Makers
1. Militarize the Frontier: Support the construction of a permanent "Security Barrier"
along the Eastern border, modeled after the Jordan-Syria border security program.
2. Sanction the Enablers: Apply Treasury sanctions to any Lebanese official—civilian or
military—who facilitates the "open border" policy.
3. The Sovereignty Test: Define Lebanese sovereignty by its ability to collect customs at
every point of entry. If the state does not control the border, it does not exist.

Conclusion: The fall of Assad has presented Washington with a generational opportunity. By
forcing the closure of the "Eastern Breach," the U.S. can finally end the era of the open-border
militia and secure the Eastern Mediterranean.
