Then you are purposefully dense.
Israel had the choice of sitting back, doing nothing while absorbing enemy attacks, or, in your words, saying "okay you want a fight, let's have one."
It is not a matter of WANTING a fight; it is a matter of being forced to either fight or be killed.
Do you honestly think Hezballah, Hamas, Islamic Jihad, and all the rest would not keep attacking and indiscriminately killing, until evey Israeli was dead, if Israel refused to fight?
I think you are arguing with someone that agrees with your postion. Sorry if I was not clear in my request for you to elaborate on the sentence you posted.
There is no doubt where the problem lies. The rest of the world has looked the other way while fathers sent their 15-year-old sons strapped with bombs about their waist into a school bus to blow off the arms and legs of Israeli school children.
