"Israeli soldiers have captured a strategic hilltop crowned by the Crusader castle of Beaufort in southern Lebanon, the Israeli military announced on Sunday, part of the most sweeping Israeli invasion in the country in decades.

The seizure of Beaufort, while hailed by Israel’s top leaders, also evoked bitter memories in both countries of the repeated battles fought there during the nearly two-decade Israeli occupation of southern Lebanon. Israel finally withdrew in 2000 after a bloody insurgency led by Hezbollah, the Iran-backed militant group.

... Now, more than a quarter century later, Hezbollah is once again fighting a guerrilla war against invading Israeli forces; Israeli leaders openly discuss a return to a long-term Israeli “security belt” in Lebanon to fend off Hezbollah attacks; and an Israeli flag flutters over the fortress at Beaufort.

Benjamin Netanyahu, the Israeli prime minister, hailed the conquest of Beaufort on Sunday as a “dramatic step” and vowed that Israeli forces would continue advancing in Lebanon. But military experts said neither move would likely stop Hezbollah from firing rockets and drones at its invading army or Israeli cities.... "

Just how far into Lebanon is Israel planning to invade, conquer and raise the Israeli flag?

The Lebanese government has no control over that part of Lebanon. Hezbolla is a state within a state with a military force greater than that of Lebanon itself.

Just like it respected the Partition map and the Green Line.

Still waiting for Lebanon to act to kick Hezbollah out of their country.
