Second - Lebanon has security forces? Wha? No, really...though I'm going to hold off on judging what's going on down there for now. Too many complex political forces at work to make a good judgment. CNN is already declaring Islamists are somehow at fault.
It does though, remind me a bit of Israel and Hamas - if this Lebanon story has suddenly blown other headlines off the map, let me refresh your memory. Israel targets homes of a Hamas politician over the weekend, killing 5 (or more). Yeah, they went after the family of a politician. And killed 5 of his family members. These aren't political or militant affiliates, but this is the future of war between nation-states and non-state actors. States will try to disrupt all forms of primary loyalty. Israel will not be held to a higher standard, as they are our petri dish for fighting terror.
Speaking of petri dishes, you might want to check out John Robb's take on the kidnapping of American troops:
The returns he was able to generate from this investment are pretty amazing: the hunt, now running into weeks, to find the missing soldiers has tied up 4,000++ soldiers, significant intel assets, and a major portion of US command's attention/focus (which naturally slows down decision making cycles).
