Finland's accession to NATO, which took place earlier this year, significantly altered the security dynamics in northern Europe, extending the alliance's frontier with Russia by approximately 1,300 kilometers (830 miles). This move also dealt a blow to Putin, who has consistently opposed NATO expansion.

In the interview, Putin questioned the necessity of bringing Finland into NATO, stating, "They (the West) took Finland and dragged it into NATO! Why, did we have any disputes with Finland? All disputes, including those of a territorial nature in the middle of the 20th Century, have all been resolved long ago."

Expressing his discontent, Putin revealed plans to establish the Leningrad military district in the region and concentrate military units there, signaling a strategic response to the changed geopolitical landscape.

Putin dismissed remarks from U.S. President Joe Biden, who suggested that Putin might escalate further, potentially targeting a NATO ally and involving U.S. troops in conflict. Putin labeled such comments as "complete nonsense" and emphasized that Russia has no interest or geopolitical motive to engage in hostilities with NATO countries.

Amid these rising tensions, Finland recently announced the closure of its eastern border with Russia in response to a spike in migrant crossings, which Helsinki has labeled a Russian hybrid attack. The closure, effective until January 14, 2024, comes as Finland grapples with the aftermath of joining NATO and the consequential changes in its security environment.

Before Finland's NATO membership, the country had already committed significant resources to enhancing border security, allocating approximately $143 million to build barrier fences along its previously less protected 830-mile eastern border with Russia. The decision to close the border for a month underscores the evolving complexities and challenges faced by Finland as it navigates the consequences of its NATO affiliation, exacerbating an already tense regional situation.
