If the Iranian lackeys wanted to kill Americans, they can do so at any time. It doesn't appear they want to be added to the targets of America list at this time.
Having read a story about a journalist who dealt with them in Lebanon, they seemed to want to avoid that. Not that they wouldn't throw in some intimidation to the journalist, they did. But then they came back and said that was merely a misunderstanding.
This is a volatile situation to say the least. If it were me, I'd have made at least one friend with a nice Lebanese Christian family. And I'd be hanging out east in the mountains as a result.
Damn good people they are. I know one family here.
Hezbollah has targeted Americans before. It's possible that they are backing off at this time as far as instant killings go, but I don't doubt for a minute that they'd take some as hostages.
