Tensions increased in Southeast Asia after World War II because of the process of ending colonialism and the Cold War. As European powers began to decolonize the region, there was a power vacuum that led to instability and conflicts among various nationalist movements and political ideologies. Additionally, the Cold War rivalry between the United States and the Soviet Union further exacerbated tensions in the region as both superpowers sought to gain influence and control.
