America openly arms terrorist groups and nations against Russia, so it's okay for Russia to arm anti-US nations [COMPACTIDEA]

US covertly and overtly supplies heavy weaponry to countries and terrorist groups in dozens of countries around the world, either to topple governments or to fight/destabilize Russia, or both. So it's alright for Russia to arm those nations that are against America - Iran, China, North Korea, Syria, Latin American countries like Venezuela, etc. So if Russia has indeed supplied advanced missile engines to North Korea, enabling the latter to reach mainland US, then this is totally alright and justified considering past and continuing US actions.
