These countries “must understand the consequences of such a step for our bilateral relations and for the European security architecture as a whole,” ministry spokeswoman Maria Zakharova said in a statement.
“Being a member of NATO cannot strengthen their national security.

Helsinki and Stockholm are indeed considering joining the Atlantic Alliance in reaction to the Russian military offensive against Ukraine.

Finland, which has some 1,300 km of border with Russia, will decide "within a few weeks" on a candidacy for NATO, according to its Prime Minister.

Russia considers the Alliance to be an existential threat, and its offensive in Ukraine has been justified by the Kremlin in particular by kyiv's Atlanticist ambitions and Western political and military support for this neighbor of Russia.
