By your logic, engaging in weapon manufacturing is the only accepted conclusion. In fact, people that refuse to do so are participating just fine, even though you don't agree with their contribution.
My logic is that refusing to engage is not an ethically superior position when the capability is necessary. Engaging in difficult, high-risk, but necessary issues as best you can is.
That doesn't mean everyone needs to work on weapons, just that the work on weapons is necessary and those that do it are not ethically compromised in some way. It's just a recognition of this without pretending not engaging is somehow more morally pure. Not engaging is just removing yourself from dealing with the actual hard ethical issues.
an interesting thought given the politics of the day. If you are not actively engaged in weapon manufacturing are you not complicit in the murder of the Ukrainian people? If you are not actively helping to supply the Ukraine army with weapons for their defense then, by your inaction, are you enabling their death?
