Which of the following is the purpose of the north Atlantic treaty organization is it a economic aid or open borders or patrolling or common defense

Answer 1

The purpose of the North Atlantic Treaty Organization (NATO) is primarily "common defense." NATO was established in 1949 with the goal of providing collective security against aggression, where an armed attack against one or more members is considered an attack against all. While it has also been involved in various missions and operations that can include patrolling, its foundational purpose is centered on mutual defense among its member states.
