The state can be seen as a major player in international relations. Many argue that the state is the foremost and most important player in global politics. It is important because the state is an operator of global politics and because global politics exists on the basis of the state.
But others argue that state power is declining today. Multinational corporations are becoming more powerful than NGOs, and state power in global politics is declining.
Simply put, the state is a political and legal entity. Each state has several features in common.
A feature of modern politics is a large number of nations in many states. These nations depend on the existence of the state. State and nation are not one. The state is an institution composed of political and legal systems. A nation is an element of cultural needs. These nations may be of different religious, cultural, and linguistic backgrounds, and the relationship between government and the nations may be weak. For example, if they do not accept their language, religion and culture, they will have a sense of nationalism about the state. They then begin to demand a separate country for their culture and try to create conflict with the government. The 30-year war in Sri Lanka is a good example of this.
Thus the importance of the state to global politics can be seen.
