This is a problem of collecting evidence about who is responsible. It doesn't address the underlying nature of the responsibility. In your hypothetical, you are the one who is responsible both for the hacking of the military network (in the context of this discussion, presumably to do physical work like killing people) and for fingering someone else. This is indeed not very different from physically committing a murder and planting evidence pointing to someone else. Yet that does not cause us to challenge the notion of responsibility for murder.
