Nationalism plays a significant role in global politics by influencing national identity and state behavior. It fosters a sense of unity among citizens and can drive countries to pursue sovereignty and self-determination. This focus on national interests often results in a desire to protect borders, culture, and economic interests. However, nationalism can also lead to conflicts, as it may exacerbate tensions between different ethnic or national groups, often giving rise to movements or policies that exclude or vilify others. Consequently, nationalism shapes both domestic agendas and international relations, affecting cooperation and conflict on a global scale.
