The general population of Gaza must pay for those they allow to rule them.
I would apply the same calculation here, based on the current administrations record.
The Arabs in Gaza voted for Hamas; the Germans did not vote for Hitler (he was appointed reichskanzler by von Papen). This is not to say the we shouldn't have bombed Germany as we did, but that Israel should bomb Gaza even worse than what was done to Germany. I suspect the people in Gaza now are more evil than the Germans were back then.
