I think it was a horrible screw up. A screw up that was a result of Israel not being capable of completing their war goals. This war, where they attack Hamas in a populated area (where Hamas actually is), and chase all the people away to another area, where Hamas remnants then follow to regroup and prepare for the next attack, is a stupid, failed idea, and events like the WCK are inevitable.
Israel didn’t have the troops and willingness to really eradicate Hamas, in the time frame they have. They are trying to be clever, using advanced weaponry, where something closer to the Red Army taking Berlin was needed (and if you don’t have the manpower and will to do that, you need another strategic goal).
Looks like Hamas will be the winner, because Israel’s plan couldn’t achieve their goal, and Hamas will take over the West Bank in short order. I think things are about to really get ugly.
(PS- I think they need a new government, because a new strategic plan is needed, and new goals. The current one is a failure and sticking with it will just waste more lives).
