US Pledges Military Support and Marine Deployment to Lebanon Under Security Agreement

The United States has made a formal commitment to send military equipment and 3,000 Marines to Lebanon should armed clashes or civil war break out involving Hezbollah, according to terms laid out in a signed accord.

The pledge, reported on June 28, 2026, represents a significant security guarantee for Lebanon as tensions remain high in the region. The agreement specifies the conditions under which American military personnel and materiel would be deployed to the country.

The commitment has drawn scrutiny from multiple quarters. Mahmoud Qamati, deputy head of Hezbollah's political council, characterized the accord as stillborn and unenforceable, dismissing any need to mobilize public action in response. He further stated the party rejects any connection between Israeli withdrawal and internal Lebanese matters, particularly regarding weapons.

Israeli sources have raised concerns about the durability of the arrangement. Channel 12 has reported that Israeli officials worry the agreement could face challenges not only from Hezbollah but also from a parallel accord between Washington and Tehran, suggesting potential complications in implementation.

On the ground, an Israeli withdrawal from two buffer zones in southern Lebanon that had been scheduled for the same period did not occur, with Israeli public broadcasters citing incomplete preparations as the reason for the delay.

Separately, official Lebanese authorities have reportedly granted Israel operational freedom within the Yellow Line, a demarcation that has long been a point of contention between the two countries.
