Yes? They fucking kill people with that stuff, do you know that? Like, literally drop explosive ordinance from the air and kill small children, sever their legs and arms, blind them, and so on. Or sometimes it burns their flesh off, or maybe just gives them cancer twenty years later.

Maybe you're okay with the notion that all of this disgusting violence and death is justifiable in the service of securing our "national interest" (i.e., our access to the natural resources of other countries), but I'm not interested in making this pretense. People who make millions, or billions, selling their effort and expertise to the US military so they can more effectively murder are ethically bankrupt. The more so because they're not doing so in service of specific objectives which you might argue are good (say, the war effort in WWII) - they are just literally supporting the ongoing murderous potential of the military.

Not to a real American.
