An "alliance" is a formal agreement between two or more parties to work together toward common goals. This can occur in various contexts, such as politics, business, or military operations. Alliances often involve sharing resources, information, or strategies to achieve mutual benefits and strengthen relationships. In international relations, alliances can enhance security and stability among nations. For example, the North Atlantic Treaty Organization (NATO) is a military alliance that promotes collective defense among its member countries. Alliances can also be formed in the business world, where companies collaborate to improve competitiveness and innovation.
