For the past few generations Israel has occupied the Gaza strip (and other areas) and the Palestinians have been doing their intifada and generally becoming resentful. Now the Israelis are pulling out and leaving them their own area. The generally cited reason is that this shorten the Israeli security perimeter and makes it easier to defend.
After decades of occupation the main Palestinian “natural” skill would seem to be rock throwing and suicide bombing. What if the Israeli end game is to give the Palestinians what they want, and then let the various groups compete for dominance in bloody fashion? This keeps them divided and busy for years and the Israelis could offer weapons and intelligence and weapons to keep the fight going (like they supposedly did during the Iran-Iraq war in the 80s). All this would leave Israel relatively secure with the Palestinians taking themslves out of the picture.
Just a thought.
