Hezbollah exists mainly to protect Iran's nuclear program by threatening to shower Israel with tens of thousands of rockets, with a potential for thousands of deaths and massive impacts to their economy. Israel's economy is it Achilles heel, no matter how robust the IDF.
The IDF is one by one eliminating Hezbollah's deterrence assets. Now that Hezbollah's quite literally being neutered, Iran is exposed, and so is its nuclear program.
Israel is tired of waiting and Iran's nuclear assets will be targeted soon.
