Global alliances are partnerships between countries, organizations, or businesses that work together to achieve common goals. These alliances can focus on various areas, such as trade, security, or environmental issues. By collaborating, members can share resources, knowledge, and expertise, which can lead to mutual benefits and stronger relationships. One well-known example of a global alliance is the North Atlantic Treaty Organization (NATO), which promotes military cooperation among its member countries. Another example is the World Trade Organization (WTO), which facilitates international trade agreements and resolves disputes. These alliances help nations address challenges that transcend borders.
