Non-interventionism or non-intervention is commonly understood as "a foreign policy of political or military non-involvement in foreign relations or in other countries' internal affairs".[1][2] This is based on the grounds that a state should not interfere in the internal politics of another state as well as the principles of state sovereignty and self-determination. A similar phrase is "strategic independence".[3]
Non-interventionism became a norm in international relations before World War I. During the Cold War, it was often violated in order to instigate revolutions, prevent revolutions, or protect international security. Many countries have since adopted their own interpretation of non-interventionism or modified it according to the responsibility to protect any population from egregious crimes.[4]
