It's all moot. Israel should stay out of Gaza unless it intends to achieve real victory over Hamas. That means the re-liberation of Gaza, and annexing it to Israel. Following that, cash payments to Arabs would be made to resettle the Gazan Arabs, or a substantial portion of them, in Arab lands. Look at a map. Strategically, Israel cannot abide a mortal enemy in the Gaza strip. But to go in, dismantle a few rocket launchers, and leave, accomplishes nothing permanent.
