Why is Israel maintaining a military presence along the Lebanese border despite the ceasefire deadline?

Israel announced it would maintain presence at five strategic positions along the border despite the February 18 deadline expiring. These locations, situated on high ground overlooking Lebanese territory, are considered vital to Israel's security. Prime Minister Netanyahu justified this decision by insisting Israel will do whatever necessary to enforce the ceasefire. The original agreement stipulated that Lebanon's military would take control of the region alongside UN peacekeepers. However, with Israel refusing to fully withdraw, the possibility of renewed clashes with Hezbollah remains high, undermining the ceasefire's stability and increasing regional tensions.
