Exclusive: TVP World in Finland – the Country with NATO's Longest Russia Border | News in Depth

Sep 11, 2025 | Finland, home to 5.5 million people sharing NATO’s longest border with Russia, is strengthening its defenses after Russia’s full-scale invasion of Ukraine. While many Finns feel confident in their preparedness, others remain wary of the Kremlin’s threats and hybrid tactics, such as the weaponization of migrants. Along the border, Finnish guards remain calm yet vigilant, even though military installations are limited, and most crossings have been closed since 2023. The country has built extensive civil defense infrastructure, including over 50,000 shelters capable of housing 87% of its population in a crisis. Finland also maintains nearly 900,000 reservists and emphasizes self-reliance, viewing NATO as only a third line of defense after its own forces and regional allies. Officials stress that preparations began decades ago, reflecting Finland’s long and often tense history with Russia.
