The question and it’s details are such that it is Russia that is doing all the aggression and not NATO. The story is other way around where NATO is violating and provoking the Russians repeatedly. The RS-28 Sarmat named Satan-2 by NATO is just another MIRV Ballistic missile but has the capacity to surpass any BMD(Ballistic Missile defence system) or Radar in the world. MIRV Ballistic missiles are there with the US too but they might not be able to dodge radars. [Quote from one commentator.]
