I don't know what sane American would be in Lebanon, but then again there's Americans who get it in their fool heads to go to active war zones all the time. Like they're fucking tourists to a war, not even to fight. Not to mention North Korea.
America has lot's Lebanese people. They're just there to visit their families. Lebanon wasn't an active war zone until Israel decided it was. Thanks to being enabled by America.
Hezbollah has been launching rockets at Israel for a year now, they were the ones who made it a war zone, Israel just decided to finally respond to being attacked.
Uh... There are Lebanese American people who want to visit their families. It's dangerous, but for many people worth the danger when their homes aren't suddenly made into active warzones.
