I understand why they're doing it (look up UN Resolution 1559 on wikipedia). But the whole thing of warning Lebanon civilians to get out by 2:00 P.M. today is just weird.
"Hey, we're coming to invade your country, just for a little while. We'll be coming in at 2:00, just so's you know."
Sorry, incursion, not invasion.
I've been doing some research into the whole thing. It's complicated: it involves Syria, Iran, Palestine, Iraq, Israel, Jordan, and a bunch of other stuff. Take a look at Chebaa Farms and try to figure out who actually owns it (The Blue Line). And then there's the factions in Syria who don't recognize the current political boundaries, but believe in Greater Syria which encompasses Israel, Palestine, Jordan, Syria, part of Turkey... it's just weird.
Then there's the whole shiite/sunni thing. Both hate Israel, both hate each other.
The U. N. is pretty much powerless. Nobody pays attention to them anymore.
