Not sure how your statement applies to the current hostilities.
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?
