Escalating Conflict in Lebanon and the Broader Middle East

Tensions are rapidly escalating in Lebanon, with Israeli ground troops crossing the border and initiating military action against Hezbollah. This conflict is unfolding against a backdrop of wider regional instability, involving Iran, the United States, and various proxy groups across the Middle East. More than ninety thousand Lebanese have already been displaced, and at least a hundred have been killed as of March 6, 2026.

Israeli Offensive and Evacuations

On Tuesday, Israeli ground troops entered southern Lebanon, building upon existing positions held for decades . Israel issued evacuation orders for dozens of villages south of the Litani River, a thirty-kilometer zone from the border. These orders were later extended to include the southern suburbs of Beirut, a densely populated area and a stronghold of Hezbollah, prompting widespread panic and a mass exodus of residents . Residents were advised to open windows to prevent shattering from potential blasts . Further evacuation notices were issued for towns in the Bekaa Valley.

Regional Implications and Iranian Response

The Lebanese front is intertwined with a larger regional conflict. Following U.S. And Israeli strikes on Iranian nuclear sites in June 2025, Iran initially responded with a restrained approach, providing warning before striking U.S. Bases. However, Iran has now stated that there are “no red lines” in its response . Tehran has retaliated against Israel and the U.S., targeting bases and installations in Bahrain, the United Arab Emirates, Iraq, Qatar, Jordan, and elsewhere. U.S. Embassies in Saudi Arabia and Kuwait, as well as the consulate in Dubai, have also been targeted.

The Axis of Resistance and Iraqi Involvement

Hezbollah, despite sustaining damage in previous conflicts, remains a key component of an “Axis of Resistance” that includes Yemen’s Houthis, Palestinian groups, and Iraqi militias . Iraqi militias, some of whom recently met in Tehran, are prepared for a “very long war” . These groups have launched attacks on U.S. Interests in Iraq, Kuwait, and Jordan, sustaining casualties in counterattacks. The Iraqi government is attempting to balance condemnation of attacks with concerns about economic repercussions, as Iran has effectively closed the Strait of Hormuz, impacting Iraq’s oil-dependent budget.

Military Capabilities and International Response

Iran faces a formidable military challenge from the U.S. And Israel, with potential support from France, Germany, and the United Kingdom. However, Iran’s ability to produce ballistic missiles and drones—over a hundred missiles and thousands of drones per month—outpaces the U.S.’s ability to produce interceptor units, at a rate of only six or seven units per month . Hezbollah has amplified its attacks, launching drones and rockets at Israeli military sites and tanks that have entered Lebanon. Hezbollah’s leader, Sheikh Naim Qassem, has affirmed that the group’s weapons are non-negotiable and called for Lebanese unity in confronting Israel .

Historical Context

The Israeli–Lebanese conflict has been ongoing since 1948 , with major phases occurring between 1978 and 2000, in 2006, and again from 2023 to the present . Belligerents have included the Lebanese National Movement, the PLO, Syria, Hezbollah, Israel, and the South Lebanon Army .
