There are several possibilities here, none of them comforting. If it’s fake news, and it could be, it may be intended to intimidate the Biden administration. If it’s not fake news, what does “unexpectedly appeared” mean? Does it mean, as the video claims, that the U.S. cannot track this submarine and its payload of 160 nuclear warheads, which would go a long way towards wiping out the U.S.? Is this Vladimir Putin’s way of saying that if the U.S. and NATO want to park their weapons and troops on Russia’s borders, he’s going to park an undetectable submarine armada on ours? Is Putin sending a message? Stay tuned.
