Alliance

An alliance is a formal agreement between two or more parties, often nations, to cooperate for specific purposes. These collaborations can involve military support, economic partnerships, or political coordination. Alliances are formed to strengthen security, enhance trade, or promote shared interests. For example, NATO (North Atlantic Treaty Organization) is a military alliance where member countries agree to defend each other in case of an attack. Alliances can also exist in business, where companies team up to achieve mutual goals. Overall, alliances enable groups to leverage their combined strengths for greater effectiveness.
