The decision to use the hypersonic missile Kinzhal, one of Russia's superior weapons along with hypersonic Zircon missile and the Poseidon torpedo, is a MAJOR DETERRENT SIGNAL TO NATO.
Read this thread to understand why this is C7 chess move from Putin.

2000 km range, Mach 10 speed, flies at the Stratosphere & is designed to evade air defense systems (Partiot, THAAD, AEGIS), makes it invincible threat. GAME ELEVATES ON ANOTHER LEVEL
