Of course then your country could lose a war because it had insufficient technology, and you'd get to wonder if you contributed to that (you would have, though so would everyone else).

Or because you didn't work on guidance systems, you could wonder if that was the reason the near miss which causes a lot of civilian deaths happened.

Or you could note that the use of military power is not really constrained by technical limitations and never has been, but the effect most certainly is, and start voting and advocating politically which would be more effective at stopping wars in every way.

But then you would have some much more direct responsibility for how the various conflicts turned out.
