A U.S.-led coalition refers to a group of countries that come together, often under the leadership of the United States, to achieve a common goal, typically in military or humanitarian efforts. These coalitions can form in response to international crises, conflicts, or threats, and they aim to enhance security and stability in specific regions. Coalitions may include a mix of NATO allies, partner nations, and other international organizations. They work collaboratively to share resources, intelligence, and strategies, ensuring a unified approach to addressing challenges such as terrorism, regional conflicts, or humanitarian disasters.
