List of interstate wars since 1945

(Redirected from Interstate war)

This is a list of interstate wars since 1945. Interstate warfare has been defined as military conflict between separate states over a territory,[1] including irregular military forces legitimized by the laws of war applicable to interstate wars due to the invasion or annexation being unlawful. This does not include civil wars and wars of independence, or smaller clashes with limited casualties (fewer than 100 combat deaths). The largest interstate war in history, World War II, involved most of the world's countries, after which the United Nations (UN) was established in 1945 to foster international co-operation and prevent future conflicts.[2] The post-WWII era has, in general, been characterized by the absence of direct, major wars between great powers, such as the United States and (until 1991) the Soviet Union.[3][4][5][6][7]

[F]or the period material to this case (1992), the armed forces of the Republika Srpska were to be regarded as acting under the overall control of and on behalf of the FRY (the Federal Republic of Yugoslavia). Hence, even after 19 May 1992 the armed conflict in Bosnia and Herzegovina between the Bosnian Serbs and the central authorities of Bosnia and Herzegovina must be classified as an international armed conflict.
