See how the goalposts now move from "arms manufacturer in general" to "I don't agree with US foreign policy."
And even assuming that's true for the sake of argument, what? Lockheed Martin, Raytheon, et al. are just supposed to shut down for good the moment one politician makes a morally questionable decision? Life is not that black and white.
You're inventing your own goal posts here, since I didn't say anything of the sort.
To repeat: if you work for an arms manufacturer, you condone killing people. Hopefully it's because you think the weapons are killing enough Nazis/terrorists/bad guys to outweigh the occasional innocent civilian, but their blood is still on your hands.
