I say this act by Hamas KILLS the concept of a Palestinian state.
Second, Israel needs to take steps different than ever before. This is NOT a terrorist act, this is an act of war, and the only intelligent act by Israel is to destroy Gaza.
So I say, give notice to the people to vacate the entirety of Gaza, giving them 72 or 96 hours to vacate, and then level the territory to the ground. Establish that this will no longer be land to be occupied by Palestinians.
And if the USA wanted to truly support Israel, I say it is time for LEND LEASE once more. Give Israel six B-52 bombers to level Gaza. Carpet bomb Gaza out of existence. End it now, swiftly!!!
