It's not israel's place as the aggressor to "assure" anything. Lebanon (and Palestine) have *at least* as much right to be safe from israel as israel has to be safe from them.
"Assuring" as used by you here should be taken in the same context as a controlling abuser "assuring" their spouse never disobeys them, or afrikaaners "assuring" that South Africans of other races have no power.
> 2. Acquire a bargaining chip ahead of a future peace agreement with Lebanon
Yes, this is territorial expansion as mentioned above.
> 3. Signal to the Iranian axis and the rest of the Middle East that it has won this war
Why would israel signal that Iran has won this war? Seems like they'd want to avoid attention on that.
Israel had previously turned a blind eye to that after the large big confrontation in 2006, but since October 7th - and conveniently, Hezbollah unilaterally joining the attack on Israel a day later - a switch was flipped and Israel went all out, as was its duty.
Sometimes preventing blowback is the best strategy.
Both russia and israel feel they should be able to unilaterally control their neighbors, and both have an equal non-right to do so. Both claim neighboring country land should be theirs, and both use military force and genocide to make that happen. Both even believe it is their religious birthright to do so.
israel and russia: two self-righteous peas in a pod.
