Russian sub mission, Cutting cables ? No Multiple internet cables exist linking things together,common knowledge. Cutting cables would definitively slow, stop certain commerce, banking, internet, so on. It would be bad, sure, but temporary @ best. All of the above could be accomplished on either side of the cable with software, hacking, half a dozen other methods. The current MSM consensus is something along the "cable" lines, Alternative news has conjecture of  accidental fire(most likely, imho) US sub fire fight,rogue sub, so on. I'm not suggesting I know what happened , just know that cutting the cable is a very unlikely possibility. Im not even sure there was a sub, to be honest. Just a buzz ,Maybe Im wrong , of course .
