The only resistance? Hamas, PLO, Iran would like to differ.
But the reality is that Hezbollah is a plague for Lebanon. An Islamic ultra conservative cult with its own militia is not a good thing. They won’t hesitate to bring the country into other regional conflicts, remember they also actively supported Assad in the civil war.
It’s very possible to condemn multiple bad groups. Israel is an undemocratic, colonial, war crime mob state. And at the same time, Hezbollah are Iran backed religious lunatics with missiles. They are not contributing to anything positive in the region. They are actively destabilizing Lebanon, which is positive for Israel.
Who do you think help arm and fund Hamas in the beginning? Ooh it’s Israel. Why? Destabilizing Palestinian unity. Who benefits? Israel.
