2004 NATO Enlargement

In 2004, NATO expanded by inviting seven new countries—Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, and Slovenia—to join the alliance. This enlargement reflected NATO’s commitment to promoting stability and security in Europe after the Cold War. By adding these nations, which had previously been under Soviet influence, NATO aimed to strengthen collective defense and foster democratic values. This expansion was significant for geopolitical relations and symbolized a united front against potential threats, reinforcing the idea that mutual defense among member countries is paramount for ensuring peace in the region.
