Finland shares a border with Russia to its east. This border is approximately 1,340 kilometers long, making it one of the longest borders in Europe. It stretches from the northern coast of the Gulf of Finland in the south to the Arctic Ocean in the north, passing through various landscapes such as forests, lakes, and swamps.

The border between Finland and Russia has historical significance, as it has changed several times throughout history due to wars and territorial disputes. Currently, the border is peaceful, and both countries maintain diplomatic relations and cooperate on various matters, including trade, border control, and environmental issues.

Russia has historically been sensitive to foreign military alliances near its borders. Finland's accession to NATO, brings the alliance's military presence even closer to Russia, potentially raising concerns about the security of their western border. This could lead to an increased military buildup in the region, as Russia may feel the need to counterbalance NATO's expansion.

Russia has expressed concerns about NATO's expansion in Eastern Europe, fearing that it could lead to encirclement. With the adhesion of Finland, another NATO member is now along Russia's border, potentially exacerbating these fears. Finland's NATO membership could be seen as a threat by Russia, leading to increased tensions and potentially damaging bilateral relations between the two countries. This could have economic, political, and security repercussions for Finland.

As a member of NATO, Finland is now under the protection of the alliance's collective defense, as stated in Article 5 of the NATO treaty. This potentially enhances Finland's security against potential threats and provides a strong deterrent against aggression.

As a NATO member, Finland will have access to shared resources, including military equipment, intelligence, and training opportunities. This could improve the country's defense capabilities and help maintain a more robust military.

Membership in NATO will boost Finland's international standing and influence in global affairs, especially regarding defense and security matters. Joining NATO will strengthen Finland's relationships with other NATO members, leading to increased cooperation and collaboration on various issues, including trade, technology, and security.
