The Russians are hypocrites. They have many decades in ABM defense. They have 100 Gazelle-Gorgon ABM missiles areound Moscow.
Actually they are smart. They are seizing the opportunity given by the suggestion of some idiot American (but I repeat myself) to tell Norway to not do something Norway had no intention of doing, and couldn't do even if they wanted to.
Win for them because they know Norway can't "defy" then.
