"Russia" targeting undersea internet cables? . . . ??
Don't bet on it. Here is what I think is far more probable:
There is war on the horizon. And any time there is a war, information control is key. The truth can kill a war in seconds flat. It is far more probable that America is fronting a line about Russia cutting cables, so that if America decides to pocket itself off from the rest of the world to control information and keep Americans in the war game, a few routers can be switched off and then called a "cable break" blamed on Russia. This would villainize Russia and keep Americans desirably in the dark in one whack, a win win for the war mongers.
I would not buy ANY line about "cables being cut", you know, at least China is honest and will state when they censor, why can't America be at least that?
