In late 2023, Israel began waging war against Hezbollah, a Lebanese political party with a militant wing that has been involved in Lebanese politics since the party’s founding in 1982. The conflict began due to the militant group’s involvement in the so-called “axis of resistance,” a group of non-state actors in the Middle East backed by the Iranian government. In September of 2024, Israel began its invasion of southern Lebanon, claiming to target Hezbollah military infrastructure in the settlements near the border between the two countries (New York Times). A ceasefire was signed in November 2024; however, both groups violated the ceasefire terms, with Israeli forces continuing to launch attacks against Lebanon.
Fighting began again on March 2nd, 2026, after Hezbollah targeted northern Israel in hopes of spurring an Israeli evacuation from occupied territory in southern Lebanon. Since its initial invasion 18 months ago, Israel has continued to expand into Lebanese territory where it claims Hezbollah is active. Expansion began with the “yellow line,” which was established in April and encompassed a larger area than Israel occupied at the time of a 10-day ceasefire signed just days prior (Al Jazeera). This yellow line method mirrors actions taken in Gaza, where the line divided the area into one sector controlled by Israeli armed forces and one where Palestinians have fewer restrictions. However, according to Al Jazeera, in Gaza, people near the line are fired upon, homes are destroyed, and the Israeli-controlled side continually grows.
This same pattern is becoming clear in southern Lebanon as, at the same time that the yellow line was established, Israeli forces and Ministry of Defense officials warned Lebanese citizens to remain north of the Litani River, an area south of the line that encompasses nearly 10% of the country of Lebanon. A week ago, Israeli forces pushed past the Litani river further north into Lebanon, and Israeli Prime Minister Benjamin Netanyahu ordered the armed forces to attack the suburbs of Beirut, the Lebanese capital (New York Times). Since the American surprise attack against Iran on February 28th and the ensuing conflict between Israel and Hezbollah, Israel has taken control of a fifth of Lebanese territory (Associated Press).
This recognizable rhythm of warfare with Israel is one of moving goal posts. Continually, Israeli military forces and government officials define lines and limits to their expansions, then proceed to violate these limits and continue their conquest. These actions violate not only conventions of trust and diplomacy, but also hard and fast international sovereignty rules. External sovereignty guarantees that all states have the right to control their own domestic affairs and protects states from intervention from external actors. The principle of external sovereignty dates back to the Treaty of Westphalia, signed in 1648 and thus enshrining this norm into the international consciousness. While there is no doubt that, under international law, Israel reserves the right to defend itself and respond to attacks, their overtaking of foreign lands and other sovereign states’ territories steps beyond the bounds of acceptable action under norms of sovereignty.
Israel states that their goal is to remove Hezbollah from power, and that their claiming of territory only extends as far as it must to reach that end. However, a large majority of the Lebanese Shia population, from which Hezbollah derives its support, is in the south, making expansion further north pointless, as these people anetlready do not support the militia group. Moreover, Israel’s blatant disregard for the principle of distinction—the requirement of states to distinguish between military and civilian targets—only pushes the population closer to Hezbollah, believing that it is “the only force capable of defending them,” (B.B.C). It is clear, then, that Israel’s invasion of Lebanon and seemingly perpetual conquest of more and more territory is actually counterintuitive to their stated agenda. Their conquest and violation of sovereignty are part of the goal in and of themselves.
The international community recognizes both the “pattern of lethal strikes in populated areas by Israel,” as well as the need to respect Lebanon’s territorial integrity (The United Nations Office of the High Commissioner for Human Rights). That being said, states have yet to take action to prevent, disincentivize, or punish this behavior. A lack of multilateral economic, political, and military pressure from the international community has allowed Israel to continue their conquest of both Palestine and Lebanon with no end in sight. Continued complacency from the world only signals to Israeli government officials that their actions will continue to go unpunished, threatening the sovereignty of every one of Israel’s neighbors. Despite calls from the official Lebanese government for international intervention, countries around the world have offered support only through words, rather than action (The Council on Foreign Relations).
In order to protect territorial integrity for Israel’s neighbors, the broader Middle East, and the entire world, tangible action must be taken to prevent intrusive intervention into domestic affairs and conquest of foreign lands. The international community owes it to the governments and people of Palestine and Lebanon to stand up for their rights as states and humans. The United Nations must go farther than condemning Israel’s actions and instead put pressure on its government and defense officials to stop their seizure of Lebanese lands and return lands to whom they rightfully belong.
Israel’s expansion into southern Lebanon extends beyond a reasonable response to the threat of Hezbollah, and infringes upon Lebanon’s sovereignty. It is important that the international community stands up for the autonomy of the Lebanese government. Continued inaction threatens sovereignty norms not just for Lebanon, but for everyone. The world must step up to ensure that territorial integrity is respected and remains central to international relations.
