I hate complexity.
My assumption is everyone hates Israel.
So...
Take out Nasrallah. Make it gruesome. Something like removing the head and Fedexing it to the Mullahs in Iran.
When 250,000 lunatics come out to vow revenge against the Israelis, MOAB the bunch.
Turn your sights to Gaza.
It will be over in an afternoon. 1 shot, 1 severed head, a few dollars for overnight delivery and a big a$$ bomb vaporizing 3 generations of terrorists.
