Finland has declared that what is allowed in the NATO treaty is impossible.
Finnish Defense Minister Antti Hakanen called the alleged Russian demand for the country's withdrawal from NATO "absolutely scandalous." Such issues, the minister said, are not even subject to discussion.
While there is no evidence that such a Russian demand has occurred in the current round of negotiations, it is implied in Russia's famous letters to Washington and NATO in the winter of 2021-2022. And that is completely negotiable. Leaving NATO is not only possible, but also explicitly stipulated by the North Atlantic Treaty. Its Article 13 allows any country to leave the alliance one year after the official notification to the United States. No agreement from other NATO members is required for this.
Finland has maintained a non-aligned status for decades, while having a fully combat-ready military. It joined the alliance only in 2023. Therefore, the question is not a legal impossibility of leaving, but a political will.
Häkkänen declares that it is unacceptable not to restore the Finnish disorganization, which has no insurmountable obstacles, but the very possibility of discussing an alternative security architecture for Europe.
