Hitler and associates, I understand, never employed suicide bombers . Auschwitz carried out its "task" without suicide bombers. This lack of suicidal fanaticism places them on a higher ethical plane, according to Harris, than fanatics who do employ suicide bombers.
The SS officials in Schindler's List were ethically superior to the Cuban rebel in Godfather 2, who blew himself up together with a captain (in Harris' ethic).
Most societies in which Jews were a not-very-powerful minority could have murdered them all. It follows by Harris logic that any Jews they did kill, they killed by accident.
Harris prattles incessantly about Hamas' charter. Does he think political parties' platforms, written or oral, are, or should be, classified as an acts of war, by international law, which would justify acts of war, like unending sieges, in self-defense?
When a hugely powerful country uses military force to impose military control and subjugation on an infinitely weaker population, Harris seems to think the latter has two "ethical" options: it can submit meekly to complete foreign control and domination, or it can fight pitched battles which would be acts of futile suicide; but if it employs the guerrilla tactics generally used by occupied resistance fighters, it is less ethical than the occupiers, because in that case it is "using human shields." In fact, since, according to Harris, suicidal attacks are the most morally vile, even the pitched battle option is ethically unavailable to the weaker population.
Thus, Harris' position is that "might makes right." The force used by the mightier occupying army to maintain subjugation of the weaker population is always more ethical than any force used by the latter in resistance to subjugation, because the latter can either engage in pitched battles which would be suicidal and therefore fanatical and evil, or it can use guerrilla-type tactics which involve "using human shields."
So Palestinians need to shut up and happily accept whatever control and subjugation and submission Israel demands. It is because of Muslim Antisemitism and an irrational love of terrorism for the sake of terrorism that they don't.
