I'm thinking that if Israel sends a large ground force into Lebanon, Hiz will fall back to Beirut. Just as the PLO did in '82. Then Beirut would be the last place on Earth an American would want to be.
If the Israelis would invade Lebanon, I could take a taxi to Haifa. :-) Okay, two taxis: one to the border and one from the boder to Haifa.
