DARPA developing universal translator for satellites

Don't be naive, in any peer-conflict between nations that could hit satellites, any civilian infrastructure is a valid military target. The only thing that holds either side back is fear of reciprocity. Power stations, merchant ships, radio stations, all of this stuff is "fair game" by the rules which actually matter. You think civilian satellites would be exempt from this, when they don't even have women and children on board? Please. All communication infrastructure, like power grids, are de facto duel use. The US military has been buying the service of civilian communication satellites for as long as they have existed. This changes nothing.

>but the UN says...

US federal law says it will invade the Hague if the ICC, or any other international court the US doesn't choose to consent to, is used against US or allied personnel.

The "validity" of a target is determined solely by the military utility of attacking it Any other standard is a joke that goes straight out the window when a major war starts, and since you're talking about American/NATO satellites being hit, you're obviously talking about a major war. International laws don't keep American civilian infrastructure safe from attack; fear of what the American military will do to retaliate is what actually matters.
