Step-by-step explanation:
NATO, or the North Atlantic Treaty Organization, was originally formed in 1949 with the signing of the North Atlantic Treaty. Its primary mission was to provide a collective defense against potential Soviet aggression and to promote stability and security in the Euro-Atlantic region.
Today, NATO's mission has evolved to reflect the changing global security environment. Its current mission is to ensure the security and defense of its members, promote stability and cooperation in the Euro-Atlantic area and beyond, and address new and emerging security challenges.
This has included NATO's involvement in a range of activities, such as counterterrorism operations, crisis management, and promoting democratic values and institutions. NATO has also expanded its partnerships with non-member countries and international organizations to enhance global security and stability.
In short, while NATO's original mission was primarily focused on collective defense against the Soviet Union, its present-day mission has expanded to address a wide range of security challenges and promote stability and cooperation on a global scale.
