Sweden becomes the 32nd member of NATO after completing the accession process. This marks a significant shift in Swedish security policy, traditionally based on neutrality. In April 2023, Finland joined the alliance as its 31st member.


  • Reason for Joining: Sweden’s decision is likely driven by heightened security concerns in Europe, particularly following Russia’s invasion of Ukraine.
  • Implications for Europe: Sweden’s accession strengthens NATO’s presence in the Baltic Sea region and potentially deters further Russian aggression.
  • With the joining of Sweden, all Baltic Sea countries; Denmark, Finland, Germany, Estonia, Latvia, Lithuania, Poland, and Sweden are now NATO members.
