Why Lebanon? Just attack Iran and get it over with. None of this other shit happens without those devils. Hamas, Hezbollah, Houthis, etc. Kill the entire IRG leadership, the Mullahs, everyone. MOAB their nuclear plants. Enough of this crap.
I think Lebanon is not full-out Islamist. I knew a Lebanese family in CA. Granddad came to US, had a little coffee shop in Michigan somewhere, eventually grew in billion-dollar shopping centers enterprise. In the generation I knew, one son was an MD (good friend of mine) and his younger brother made a great living and life as a movie producer.
They hardly fit the mold of Hamas, Hezbollah, etc.
