International law decreed that Hezbullah stay away from the Israeli border. And also not lob missiles at civilians. There certainly are rules, and Hezbullah has thumbed their nose at the rules. So the Israelis are saying, if they aren't going to play by the rules, okay then, neither will we.

Let's say there's a one-on-one basketball game, and both sides agree to the rules, but then one player arbitrarily decides not to play by the agreed-upon rules and comes to the game with a pistol and starts taking shots at the other player. You expect that player to continue the game normally and just accept whatever bullet wounds he may suffer? I sure wouldn't.

Airports and roads are where Hezbullah gets their supplies from Iran and Syria. Choke off the supply lines, win the battle. Troops can't fight very well when cut off from their supply lines, and it's psychologically demoralizing when your supply lines are cut. These guys aren't building the missiles they're lobbing into Israel in some basement.

Not sure why you feel the need to defend attacks on Hezbullah. Have you forgotten, they were the ones behind blowing up 270 or so U.S. Marines? If they get their asses tromped, great. It's sad that they're hiding themselves among civilians, but they aren't following the Geneva Convention, or much of any other rules either, so that's the way it is.
