Oh, the Hamas police may indeed be legitimate targets, once one decides to start shooting. Likewise, all Israeli governmental personnel at all levels right down to traffic cop would be legitimate targets for someone who decided to attack Israel...from that someone's point of view only, I mean.

USAAF pilots in WWII were given clear instructions in 1943-45 to strafe and attack ANY civilian target that would constitute part of the German economy/infrastructure. That amounted to every civilian, every farm animal, every vehicle, everything period. An American flying ace, upon being given those instructions, remarked to one of the other pilots, "I hope to God we win this war, because we're in a whole load of trouble if we don't." And they would have been. They were committing war crimes.

War is the complete cessation of what we think of as normal morality, and it is the sanction of mass murder. Whoever does it, that's what it is. To pretend otherwise is the business of propaganda ministers and politicians generally, but the ordinary people in the bombsights are not fooled.

If the Muslim fighters had anything like the firepower that the Israeli armed forces do, then of course they would use it similarly on Israel, and you'd have many thousands of dead Israelis, not just a handful.

What I am not impressed by is the continual attempt by proponents of one side or the other to convince the world that they are morally better than the people they are fighting. They're not.
