Forming alliances impacts international relations by enhancing diplomatic, economic, and military cooperation between countries. Alliances can provide collective security, deter aggression, and foster collaboration on various global issues, such as trade, climate change, and human rights. They shape power dynamics by creating strategic partnerships, enabling nations to project influence more effectively. However, alliances may also lead to tensions with non-member states and can escalate conflicts if not managed carefully. Consequently, forming alliances is a critical aspect of foreign policy strategy.
