历史上,两个或两个以上的国家结成军事联盟以对付共同敌国的现象,屡见不鲜。两次世界大战都是以军事联盟的形式进行的。战后的许多局部战争也是联盟战争或带有联盟性。冷战结束后,军事联盟在世界安全格局中的地位和作用日益突出,其内容和形式也呈现出许多新的特点。 Historically, it was not uncommon for two or more countries to form a military alliance to counter the common enemy. Both World Wars were conducted in the form of military alliances. Many local wars after the war are also coalition wars or alliances. After the Cold War, the status and role of the military alliance in the world security structure have become increasingly prominent. The content and form of the military alliance have also shown many new characteristics.
