> I don't see how the FCC even has jurisdiction over this. I guess they have jurisdiction over communications with satellites within the US, but not over the satellites themselves. And practically speaking, they have no enforcement capabilities in this realm.
They have jurisdiction because they have historically had jurisdiction. If not the FCC, then some other agency would do it.
And methinks you underestimate the enforcement capability of any US government agency. They can simply ban people, companies or countries from doing business with the US government. For something like an aerospace business, no US government business means bankruptcy.
And that's just to start. This can escalate into things like export restrictions, restricted countries, or munitions export controls. And once it's in the realm of munitions, the guys with guns can show up.
