# Finnish parliament backs exit from Ottawa Treaty in 155-18 vote
Finland’s parliament has voted to withdraw from the Ottawa Treaty, the international agreement banning anti-personnel mines, in a move that underscores how the war in Ukraine is reshaping security policy across northern Europe. The measure passed 155-18, a wide margin that signals strong parliamentary backing for a decision framed by supporters as a response to the threat posed by Russia.
The vote is politically significant because Finland has long been one of the countries most associated with careful, rules-based security policy. Leaving the treaty marks a major shift in that posture. The lawmaker tally also shows that the question was not close: only 18 members opposed the withdrawal, while the broader chamber supported it by an even larger margin on related legislation, 157-18, according to Helsingin Sanomat.
The justification for the decision is tied directly to national security. Finnish leaders have argued that Russia’s behavior in the region has changed the risk calculus and that the country needs more freedom to prepare its defenses. The Ottawan framework, which bans the use of anti-personnel mines, has long been part of a wider effort to reduce the humanitarian toll of landmines after armed conflict. Finland’s move therefore reflects a tension between military planning and humanitarian restraint.
This is not a symbolic debate. Anti-personnel mines are among the most controversial weapons in modern warfare because they can continue to injure civilians long after a conflict ends. That is why the treaty exists, and why withdrawing from it draws attention beyond Finland’s borders. Supporters of the exit are essentially arguing that the threat environment has changed enough to justify regaining an option that many states have previously renounced.
The vote itself also reveals something about domestic politics. Helsingin Sanomat reported that deputies from the Left Alliance and seven Green members voted against the move, along with Eva Biaudet from the governing Swedish People’s Party. The split shows that even in a broadly supportive parliament, there remains a clear humanitarian and political minority warning against abandoning the treaty.
Finland’s decision will be watched closely across Europe, especially by states on or near Russia’s border. The country’s geography makes it sensitive to military developments, and the vote suggests that deterrence thinking is now driving policy choices that would have been politically harder to make in previous years. The change may also influence debates in other capitals that are reassessing defense doctrine in light of the war.
The wider implication is that treaties once treated as durable may now be vulnerable when regional security perceptions change. Finland is not alone in revisiting long-standing assumptions, but a parliamentary exit from a treaty banning mines is a stark example of that shift.
What the vote shows, more than anything, is that the balance between humanitarian commitments and perceived military necessity is being recalculated in real time. Finland has chosen to give the military wider room to maneuver, and it has done so with a strong legislative mandate.
Finland’s move may also carry symbolic weight beyond its borders. For countries that border Russia or sit close to conflict zones, the vote will be read as evidence that the security environment has changed enough to override older arms-control commitments. That does not settle the moral question, but it shows how quickly treaty politics can shift when defense planners see the threat picture differently than humanitarian advocates do.
