Were you discouraged?
I never really saw a whole heck of a lot of people saying Israel did not have the right to retaliate against Hezbollah or Hamas.
The problem Israel has is that a lot of their actions were being percieved as going further than targettign Hezbollah.
And the you've got the complaints of nobodies like me who worry that when the dust settles, the attitudes of both sides won't have changed one bit, and really nothing will have been done to fix the problem, beyond a temporary fix to the symptoms, which if taken too far will just worsen the underlying problem.
