An Israel with Hezbollah on its border attacking them for 11 months straight; and moving forward threatening to to attack them anytime they do something Hezbollah doesn't like is not an Israel that can thrive. Hezbollah has shown themselves to be an existential threat to Israel's existence, that cannot be ignored moving forward.

Israel pretty much has to do whatever it takes to take away Hezbollah's ability to intimidate, threaten and attack them. It is going to result in a lot of bad for everyone except for the IRI (especially the people of Lebanon); but Israel literally doesn't have a choice if it wants to be a functional first world country that thrives.

Now if there is a diplomatic solution where Hezbollah agrees to abandon the border of Israel or better yet dissolve; then that is preferable. But if Hezbollah refuses to abandon the border at a minimum, Israel literally has to do what it takes to neutralize the threat. Even if it "doesn't do much good."

I mean, if you are radical Islamists sycophant and want Israel to be destroyed, and dont care how many people are killed and nations destroyed in the process, then carry on. But if that isn't the case, at some point you have to accept the IRI and its proxies are presenting an existential threat to Israel, and at some point will be dealt with as such.
