Interesting thought. In the end, this is an ethical question: How much pressure is justified to put on the general population for supporting their leaders?
My feeling is that your perspective, likely shared by people like Bomber Harris or Netanyahu, does not match most peoples intuition nowadays.
I beg to differ. Accepting that tens of millions in Germany supported Hitler frenetically, thus declaring themselves enemies of everyone who was a Jew, a Democrat, a Citizen of any neighbouring country etc.pp., doesn’t mean that bombing cities to the ground is morally or legally justified, as long as there are other alternatives (and there have been, both for Harris, and for Netanyahu). The point really is: most Germans saw themselves as enemies of Freedom, Equality, and Peace. Both inside and outside of Germany. You cannot treat someone as a friend who’s violently proving the see you as the enemy.
