As someone involved with the industry, this is my take. The work defence contractors do and will continue to do is a measurable positive in the world. This work generally falls into three categories: First is projects that make the lives of armed forces personnel easier. There is no moral or ethical hazard with these projects. They simply are making it so that pre-existing work, often non-combat work, is less tedious. Second is projects that actively protect the lives of armed forces personnel and assets. Why would somebody have any reason to feel anything but pride in their work when they know that the only things it could ever do is save lives. Third is the arguably morally shaky stuff. Weapons technology would fall under this category. The thing people seem to miss about this category however is what new projects' goals are. Very rarely is it ever to create a more lethal weapon. Almost all development of this kind focuses on either making existing technology cheaper, more precise, or have increased range. In the first case, you could argue that it makes the weapons more likely to be used which is fair however if a weapon system is in active use already, it is unlikely that a cheaper version would do anything other than bring down operating costs. In the second case, these projects are actively making these weapons safer. Look at the Hellfire R9X as a prime example. This weapon sole purpose is to minimise casualties and minimise damage to the surrounding area. Finally the third and last case I mentioned. Increasing range is important for force projection reasons but the most immediate benefit is that it allows armed forces personnel to be further from danger. These people would be in this fight regardless but now they are able to operate from a safer distance instead. Weapons tech gets a bad rap for obvious reasons but I see that as mostly having been a relic of a past era. Nowadays there isn't really any reason to make more lethal weapons. We already have those and you can see a steady trend in new military technology towards lower risks, costs, damage to the surroundings, and minimising civilian casualties. Additionally, in my experience, you generally have a choice whether you work on a project or not. Leadership fully understands what they do as an organisation and get that some people may not be comfortable with doing certain projects. If you can't conscientiously work on a certain type of project, simply say so and leadership will take that into account when planning personnel assignments for projects. TL;DR Armed conflict and existing weapons will never go away. What we as a society(namely the modern purpose of defence contractors) can do instead is make armed conflict less dangerous to those caught in the crossfire and those who risk life and limb to defend our countries.
