North Atlantic Treaty Organization

Definition

The North Atlantic Treaty Organization (NATO) is a military alliance established in 1949, primarily as a collective defense mechanism against potential Soviet aggression during the Cold War. It was founded on the principle that an attack against one member is considered an attack against all, thereby promoting mutual defense and cooperation among its member states. NATO played a crucial role in shaping the post-World War II security landscape, reflecting the tensions that emerged following the Yalta Conference and the division of Europe into Eastern and Western blocs.
