Lebanon's inability to expel a diplomat raises questions about disarming Hezbollah.

Lebanon announced the expulsion of Irans ambassador following regional tensions but he remains in the country three weeks later highlighting the governments limits in enforcing decisions and raising concerns about controlling Hezbollah and maintaining national security.

On March 24, Lebanon announced the expulsion of Iran's ambassador to Beirut, Mohammad Reza Sheibani, marking a significant diplomatic move amid regional tensions. Despite the official decree, Ambassador Sheibani has not left the country and remains inside the Iranian embassy three weeks later. This impasse has forced Lebanese authorities to consider legal measures to enforce the expulsion, demonstrating the limits of Lebanon’s authority in addressing foreign diplomatic presence.

The expulsion followed Hezbollah's recent attacks and subsequent Israeli retaliation, reflecting a strategic attempt by the Lebanese administration under President Michel Aoun to reduce Tehran's influence in the country. While intended as a strong signal of Lebanon's support for Israel, the inability to enforce the ambassador’s removal has revealed substantial constraints in Lebanon’s political leverage.

Diplomatic and Security Challenges

Lebanon had pledged in 2024 to disarm Hezbollah, a Shia militia supported by Iran. However, the ongoing presence of Ambassador Sheibani underscores the government’s difficulty in implementing decisive actions against Tehran-backed groups. In parallel, Lebanon's first direct negotiations with Israel in Washington faced limitations in providing effective incentives to halt regional hostilities, as Hezbollah's operational resilience continues to influence the dynamics of conflict in the area.

Hezbollah’s Military Strength

The Islamic Revolutionary Guard Corps (IRGC) has deployed officers to assist Hezbollah operations, enabling more dispersed and elusive military actions. Hezbollah has successfully concealed weapons from both the Lebanese military and Israeli forces. Supply lines extending through Syria remain operational despite the collapse of former regimes, sustaining the group’s capacity to launch missile attacks targeting Israeli communities. While the Israel Defense Forces (IDF) retain an advantage and have neutralized some short-range missile threats, preventing Hezbollah from regrouping near the border requires ongoing Israeli military presence.

Limitations of the Lebanese Armed Forces

The Lebanese Army faces considerable obstacles in confronting Hezbollah directly. Historical performance against armed sectarian groups shows limited capability. Army commander Rudolph Haykal has prioritized troop safety and minimized direct engagement with the Shia population, which constitutes about one-third of Lebanon’s population. Analysts caution that forcibly disarming Hezbollah could trigger widespread conflict or even civil war. Iran continues to support Hezbollah as an active military entity capable of engaging Israel, while Israel seeks to constrain its operations along the border.

Political and Regional Implications

Lebanon’s government has undertaken talks without Hezbollah’s consent, a step criticized by Tehran, which warned of severe security consequences. The continued presence of Ambassador Sheibani in Beirut exemplifies the diplomatic deadlock and highlights Lebanon’s internal limitations in enforcing national decisions against influential foreign-backed groups. The situation raises broader concerns regarding regional stability, the enforcement of international law, and the potential for future conflicts involving Israel and Iran on Lebanese territory.

The deadlock emphasizes the complex balance Lebanon must maintain between its internal political structures, Hezbollah’s military capabilities, and the broader regional power struggles. As diplomatic and military tensions persist, Lebanon faces an ongoing challenge in asserting control over both foreign diplomats and domestic armed groups, impacting long-term security and political stability in the Levant.
