This hasn't been possible at all. Hezbollah was literally the only political entity with any strength in much of Lebanon, especially the south, running things like schools/security/police etc. It became the dominant force in Lebanese politics not for the hate/religion/conquest of Israel/Jews etc, but because it was…a sole actor that exterminated other threats to it's rise to power.
All that is why disarming/disempowering them became a political and practical impossibility.
Now that could change (perhaps even with Israel's further help), but the real colonizer has been/is the Iranian migration of Shia/money/weapons/drug trafficking into Lebanon/Beirut. It will be fascinating to see how this plays out from here, hopefully somehow less tragic than the past 40 years for Lebanon.
I've worked with/spoken with several doctors with Lebanese roots and it really seems like it was a great place, before all this crap happened.
