I'm not a pacifist, but I wouldn't work in any place related to the US military for the simple reason that it is mostly used to wage wars of aggression these days, or provide materiel to other countries that do. Stop doing that and then we can seriously talk about defensive military tech. I left NVIDIA in part because it is too heavily involved in these things (and Palantir and Anduril specifically).

Regarding this specifically:

> Would it be facilitating injury if the AI is used to stop an ISIS linked attack in our homeland?

it again depends on what exactly said AI does. If it's used to surveil most people most of the time, for example, then that probably does reduce the odds of an ISIS-linked attack on US, but the surveillance itself would be a greater injury at that scale.
