Russia is really upset that we (the US) had a successful test flight of a navigable supersonic bomb, you know the one where it can reach anywhere in the world in a hour after launch using course and target changes inflight (think joystick).
It upsets the balance of power cause Russia doesn’t have it. If one of the Clinton’s were in office, China would have thousands of them.
Russia is upset Obama hasn’t cried “Uncle!” And now Moscow intends to collect, with interest.
