Washington has long pretended that Lebanon is a sovereign state. Beaufort Castle just proved otherwise.On May 31, 2026, the Israeli military captured Beaufort Castle and the surrounding ridge in southern Lebanon. The operation marked Israel’s deepest ground advance since the 2000 withdrawal from the security zone and followed a wave of repeated Hezbollah rocket and drone attacks against northern Israeli communities.Beaufort Castle sits atop one of southern Lebanon’s most commanding ridges overlooking the Litani River and the Nabatiyeh plateau. From these heights, Hezbollah maintained surveillance and launch infrastructure capable of threatening Jerusalem’s northern border. Control of such terrain is not symbolic. It is decisive.

Yet, this is not the first time Israel has fought for Beaufort. In 1982, Golani Brigade forces seized the fortress from the Palestine Liberation Organization terrorists during the First Lebanon War. Today, the adversary is different, but the threat’s physiological scheme remains unchanged.

Hezbollah is Tehran’s most capable proxy, armed with precision missiles, drones, and intelligence networks built with billions of dollars of Iranian investment. Yet, Beaufort demonstrates the limits of proxy warfare against terrain, conventional, and multidomain military power.
