> Then, ask if this bombing was part of group A or group B.

false dichotomies are a common rhetorical method (and sometimes useful) to argue your way to a moral justification, but that doesn't make them reflect reality

There is no A and B. You want to force a situation where B is pure good intent and we either have to choose that or choose A where there is only bad intent. The reality is, this war is about ego, power and money as much as it is about any "good intent". The decisions to start the war were made with a full knowledge of the risks and costs it would entail, with almost all of those being externalised to other people than those taking the choices.

Nobody taking those choices should get to just opt out of moral responsibility with some easy "A / B" logic.
