Social Security Numbers were never intended to be used the way they are. They were expressly for identifying you to the Feds for the purpose of SSI. Business just looked at that and said “hey, that’s a good way to identify people” and ignored the feds when they asked politely for them to fucking not.
If the planes had entered sovereign airspace, sure. They synopsis says the Russians were flying in international airspace, which usually means it’s not under the sovereign control of any nation and the Latvians would have had no basis to fire on the Russians.
Personally, I’d love to see the Russians try to stunt their way into someone’s airspace and get dick slapped for it, but I doubt that would happen.
