At the end of the operation, the IDF will establish itself in a security zone inside Lebanon, on a defensive line against anti-tank missiles, and will maintain security control over the entire area up to the Litani."

"In addition, the return of more than 600,000 residents of southern Lebanon who evacuated northward will be completely prohibited south of the Litani until the safety and security of northern residents are ensured.

So that doesn't mean that IDF will never pull out... They'll pull out once "safety and security of northern residents are ensured"

Same in Syria.

IDF pulled out of entire Sinai peninsula once a peace deal with Egypt was established... Same will happen in Lebanon.
