Why do people post non-game related, flame-inspiring messages on a game centric web site?
Answer to both: I don't know.
Personal opinion on former question:
I'm guessing Israel thinks that Hezbollah terrorists in Lebanon are trying to hurt them - and Israel is fed up with it.
At the same time, Lebanon doesn't seem to care that Hezbollah terrorsits hang out in their country and carry out attacks against Israel.
Do I think it's right that Israel doesn't care that it is beating up Hezbollah terrorists on non-Israeli soil? Nope.
Do I think that a country should be able to defend it's borders, and attack its enemy before it crosses its borders? Yup.
Is it a confusing and hard subject to dissect properly? Absolutely.
The U.S. knows what's going on and mentions to Israel to cut down on attacks, but is not actively going to butt-in. Why? My guesses are:
1. The U.S. already has it's military in other parts of the World, and getting involved in another clash is probably not in it's best interest.
2. The U.S. will not be drawn out by Iran in a larger war, who backs Hezbollah.
3. Finally, The U.S. knows that its probably pissed off enough countries by now, why piss off even more...
