Sweden formally joined NATO (North Atlantic Treaty Organization) on March 7, 2024, becoming the 32nd nation to do so. Sweden’s membership, which follows that of neighbouring Finland, is a consequence of Russia’s invasion of Ukraine. This move marked a major change in the country’s foreign policy and could influence the course of the ongoing conflict between Russia and Ukraine. Membership marks a clear break with the past when for more than 200 years Sweden avoided the military alliances and adopted a neutral stance even in the war times. Swedish Prime Minister Ulf kristersson handed over the final documentation to the US government on 7th march. This was the last stage in prolonged process in gaining support for joining the military alliance.
