Alternatively: Military decisions (in the US) are already overseen and approved by political leaders and they can make judgements on a case-by-case basis, rather than blanket war=good/bad.

The US has not had a great track record here, even in my lifetime, but in a world where our adversaries are not going to have these same qualms, I think it is necessary for the US to build this technology, and if you accept that it is necessary for someone to build it, I think holding your nose and saying you want to be as far away from it as possible seems hypocritical.
