You can disagree with the bad decisions of those superiors, but the service men and women will be there fighting regardless of whether it was right or wrongApologies for invoking Godwin's Law, but this is quite precisely where the analogy is applicable.
From The Twilight Zone episode "Death's Head Revisited":
"They just heard you offer the apology for all the monsters of our time . We did as we were told, we functioned as ordered, we merely carried out directives from our superiors. Familiar, is it, Captain? It was the Nazi theme music at Nuremburg. The new lyrics to the Gotterdammerung. The plaintive litany of the master race as it laid dying.
We did not do, others did, or someone else did it.
We never even knew it was being done or
We did it, but others told us to."
I now cringingly await the downvotes.
