Finland's parliament has finally followed through with a previously threatened move to reverse its decades-long ban on nuclear weapons. The June 17 vote to lift the ban in effect legally authorizes the Nordic country to receive, transport, and facilitate the movement of nuclear weapons on its territory as part of allied operations, with the representatives' final tally at 125 to 61.

Finland officially became the 31st member of NATO in April 2023 - having abandoned its historic neutrality in the wake of the Russian invasion of Ukraine, in what was among the fastest accession processes in the Western military alliance's history. Now it is already willing to host allied nukes on its territory, making it a target of Russian retaliation.

Moscow has long warned against such an ultra-provocative move. The Kremlin said Monday that this requires a response - given also the fact that Russia and Finland share an over 800-mile long border, which is made up largely of Arctic frontier.

"The results of the vote represent both bright and unflattering victory of the blind Russophobia of the past few years over what we have always viewed as pragmatic sanity in Finland," said Russian Foreign Ministry spokeswoman Maria Zakharova.

“And let nobody doubt that [response] measures will be taken timely and effectively. In this light, the Finnish people need to think whether this decision made by their elites will actually enhance security in Finland itself,” she added.

As a start, Russia has moved to shutter more rail crossings to NATO states, including Finland - which is to further severely impact trade:

Since the Ukraine war began, and in context of ratcheting tensions with NATO over its military support to Kiev, Moscow has steadily militarized its border with Finland.

The most significant source of NATO's nuclear-sharing program is the United States. But lately France has expressed a desire to station some of its atomic arsenal in partner countries, and this could include in Finland, Sweden, Denmark and others.
