The whole defense industry leaves a bad taste in my mouth. Once you peel the narrative that we are supposed to be the good guys (hint: in some/most cases, we are not), you realize that you really just help to kill people.
Once those people will realize that they cannot win without machines and replenish the human resoruce fast enough, it becomes a game of who gets bankrupt first loses the war. If your country doesn't do it, China and Russia and Iran will.
