We're all simplifying things a little considering this isn't the place to write a thesis, but I think I understand where you're coming from.
Israel was not attacking Lebanon, they were attacking Hezbollah.
Whether Israel was "directly" attacking Hezbollah (I've been seeing it spelled Hizbollah recently by the way), Lebanon and its people have been taking a heavy toll. I have a friend and her family that are trapped there currently. The infrastructure is blown to shreds, don't mistake attacks on Hezbollah as not being attacks on the state of Lebanon. The Lebanese people are screaming to the world to get this to stop. The country and it's people are basically held hostage in all of this. Lebanon is basically a brand new country that was just starting to get its bearings. Beruit was a hopping place and considered last year to be the one of the top 10 night life spots in the world. It's an amazing city and was really starting to come back into its own.
The Lebanese army was supposed to be controlling the areas around the border but I'm not even sure they are relevant to the discussion.
And the UN was suppose to be overseeing this part of the country. As we all know they did a heck of a job. Who didn't despise the pictures of the Hezbollah flag flying next to the UN flag at one of the UN's main observation posts. Syria still has a strangle hold over Lebanon, and many saw Hezbollah's control of this part of the country as there only buffer to an Israeli attack. So they were allowed to flourish. Anyway, Hezbollah is stronger than its military at this time.
4 years ago. The US tried to sell Israel large enough bunker blaster bombs, but were turned down at the time by the general who is now leading this campaign for the Israelis. They know where a majority of the rockets are being stored and fired from, but they don't have strong enough weapons to reach them. That's why a rush order was placed a few weeks ago by the Israeli's for the same weapon they said they didn't need previously. We'll probably see another go around here in the next few weeks once they get these in hand.
It seems to be coming out. A little each day. This was a trial run to see what would happen if we were to go into Iran.
