Stay safe.
I'm sure the Israeli army wouldn't stop a U.S. airlift of its citizens by helicopter (possibly to Cyprus) if things start to deteriorate in Beirut. The IDF has very little reason to bomb Beirut hotels filled with western guests, and would leaflet the area telling guests to leave before attacking, in any event. You're probably in the safest place you can be right now, all things considered.
Amazing ping.
