There's a ton of other wrong in your comment (as if Hezbollah, alone, hindered Lebanon from being a functional state and not the decades of war and brutal massacres of their civilians), but let's focus on the main thing.
As far as Lebanon goes, decades of wars are mainly a result of Lebanon's dysfunctional sectarian political system. But having Hezbollah run around and exchange fire with Israel doesn't improve the already bad situation.
Decades of wars have nothing to do with Israel invading the country and installing the extreme right wing Fascist inspired Phalange party into power after 1982? The very event which led to the founding of Hezbollah? Okay
The Sunni world is mostly fine with Israel, other than Hamas of course, which is why Hamas had to work with Iran (although it seems like it backfired on Iran)
Egypt, Jordan, UAE, Sudan, Bahrain and the Saudis (through back channels)
It's just a fact, there's absolutely nothing ridiculous about what I said, if anything Sunni regimes are more worried about Iran than israel.
