Nationalism is an endless thing. It must be inherited continuously through education, slogans, and of course the existence of ‘others’. In the context of inter-state relations the existence of ‘others’ will become more complicated if the national identity of other nations has come into contact in open conflict. In other words, ‘others’ would be considered an antagonist if history presents a collective memory of inter-state conflicts.
In Southeast Asia, conflicts between nations are not new. The confrontation between Malaysia and Indonesia at the end of the Old Order is one example. However, since the establishment of ASEAN 50 years ago, open conflicts between Southeast Asian nations incorporated in ASEAN have almost never been heard. This is because the countries incorporated in ASEAN agree not to interfere with the sovereignty of other countries in politics or ideology. With the agreement they hope to create peace in the region of Southeast Asia.
