US must ‘force’ Israel to change its policy on Lebanon

The escalating tensions between Israel and Lebanon have reached a critical juncture, with the U.S. now positioned as a potential mediator—or enforcer—in a fragile regional dynamic. The prospect of Israel withdrawing troops from southern Lebanon, even symbolically, underscores a rare moment of diplomatic leverage for Washington, but it also reveals deeper fractures in regional security architecture. Historically, southern Lebanon has been a flashpoint, particularly after Hezbollah’s rise post-2006 and its sustained military presence near the Israeli border. The U.S. push for restraint comes as Iran’s regional influence, particularly through Hezbollah, remains a central concern for Israel and its allies. A U.S.-Iran détente, however tenuous, could temporarily ease pressure on Lebanon, but it also risks sidelining Lebanese sovereignty, a country already grappling with economic collapse and political paralysis. What makes this moment significant is the shifting calculus of deterrence. Israel’s military posture in Lebanon has long been justified under the pretext of countering Hezbollah, but the group’s integration into Lebanon’s political fabric complicates any unilateral action. The U.S. intervention suggests a recognition that sustained conflict could spiral into a broader regional war, especially as Iran and Israel exchange strikes beyond Lebanon’s borders. Yet Washington’s ability to "force" Israel into concessions is constrained by domestic political pressures in both countries. Israeli Prime Minister Benjamin Netanyahu faces right-wing factions demanding a harder line, while the U.S. must balance its strategic interests with its role as Israel’s primary backer. The next phase could see a phased Israeli withdrawal, contingent on Hezbollah’s reciprocal moves—a delicate balance given the group’s ties to Tehran. Alternatively, a breakdown in negotiations might lead to a resumption of low-intensity clashes, testing the durability of the U.S.-Iran deal. The broader trend here is the increasing militarization of diplomacy in the Middle East, where regional actors leverage ceasefires as temporary fixes rather than sustainable solutions. For Lebanon, already a bystander in its own fate, the stakes are existential: will it remain a battleground for proxy wars, or can it reclaim agency in its own security? The answer may hinge on whether Washington’s push for stability outlasts the next crisis.
