If hezbollah isn't a terrorist organization, then that provides even more legitimacy to Israel fighting back against attacks against Israeli cities and citizens. If Hezbollah is a "legit" organization, then that legit organization is facing the understandable consequences of lobbing unguided weapons into random population centers.
So, which is it? Is Israel attacking a terrorist organization that cannot be controlled by a legitimate lebanese government, or is Israel attacking a legtimate organization that has been carrying out attacks against Israeli population centers? It seems like either way, it's a legitimate reaction to a lethal threat.
When a snake bites you in your own yard, you don't ask for it's opinion. You burn it out. If the snake bites you and retreats to a nest in your neighbors yard, and your neighbor refuses to burn out the snake, you still go in and burn out the snake.
The jackprettythang 3 doors down pledging to avenge the burned out snake is likely just a distraction, so ignore him unless he attacks. If he does, then he's just another snake to burn out.
