Yeah Hitler had a similar plan to defeat the Soviets with a climatic battle at Berlin. Hopefully it works out just as well for Hamas.
A nice conclusion to this affair would be a nice low yield cobalt bomb on Gaza City where no one is killed but the entire city structure is blown away. Oh wait, the UN would then send housing to house the terrorists and make the USA pay for it. Oh well, a nice low yield neutron bomb then, all the Hamas thugs disappear and the city stays!
