Although I'd be very surprised if there weren't a lot of Iranians guiding the local terrorists in Lebanon they may not be the only Farsi speakers there. The first comment to this post at Captain's Quarters claims "Hizbollah in Lebanon, is a totally Shia, mainly ethnic Persian organization (Iranian Shias have been settling and inter-marrying in the Lebanese mountains for 200+ years, with their fellow Shia's there)" and the poster sounds like he knows what he's writing. This is the first I'd heard that Hizbollah in Lebanon not only wasn't Sunni but also mainly wasn't Arab. One more reason the usual suspects haven't jumped to their support if true.
Sort of an Iranian colony on the Med.
