I think that in a war between Israel and Hezbollah two things are certain.
Hezbollah would eventually win.
The people of Lebanon would suffer greatly.
The ideal solution to all this is for Israel to stop its genocide. If it comes to war between Hezbollah and Israel I have no doubt about who the final victor would be, but just like the last war, while the IDF will lose, they will extract a horrific price.
Israel is desperate to record a win.
They have not been able to demonstrate victory in Gaza despite taking over practically the entire territory. They have not been able to demonstrate a win against Hezbollah despite lobbing missiles back and forth for months. They have not been able to record a win against Iran despite blowing up an oil pipeline and (mabie) assassinating a president.
Even assuming the political leadership in Israel wanted to end this conflict (they don't) they can't really de-escalate until they've "won" something.
If Netanyahu were truly a statesman and a Patriot, he could in this conflict and shoulder the burden of defeat. Give Israel away to deescalate the situation and save face. Unfortunately for everyone involved Netanyahu may be a nationalist but he's not a patriot.
