North Atlantic Treaty Organisation (NATO)

Formation: Established in 1949, NATO (North Atlantic Treaty Organization) aims to enhance mutual defense and collective security among member countries. Established amidst Cold War tensions, NATO emerged as a bulwark against Soviet expansion. The signing of the North Atlantic Treaty by 12 founding members formalized the alliance.

Headquarters: The main headquarters of NATO is located in Brussels, Belgium.

Membership Expansion: Sweden officially became the 32nd member on March 7, 2024, following the inclusion of Finland in the previous year.

Collective Defense: NATO’s core principle is Article 5, which states that an attack against one member is considered an attack against all members, triggering a collective defense response.

Recent Members: Montenegro joined in 2017, and North Macedonia in 2020, marking recent expansions.

Geopolitical Significance: Sweden and Finland’s NATO membership is of strategic importance, given their shared 830-mile border with Russia, contributing to Western military alliances.

Purpose: NATO’s primary objective is to promote mutual defense, security, and cooperation among member nations, fostering stability and peace in the North Atlantic region.
