You are not mentioning why Hamas starts the cycle time and time again: a young population (http://en.m.wikipedia.org/wiki/Demographics_of_the_Gaza_Stri...), continuously harassed by Israeli actions that Israel deems necessary for the security of its population. Those rockets are lethal, but also just signs of frustration. To me, this conflict looks like a twelve year old having an argument with a four year old. The twelve year old can harass the four year old with words until the four year old starts kicking/screaming/biting. When you force them apart, both will claim the other started it, and both will, in a sense, be right.

This area of the world has found a local optimum that isn't very optimal and that nobody wants, but that nobody sees a way out of, either.
