Diplomatic negotiation differs from military intervention primarily in its approach to conflict resolution. Diplomatic negotiation involves dialogue and compromise, where parties attempt to settle disputes through communication and agreement. This method is usually favored as it aims to prevent escalation and maintain peace. On the other hand, military intervention entails the use of armed forces to achieve political objectives and may result in violence and long-term instability. While negotiations seek cooperation and mutual benefits, military actions often have significant consequences, including loss of life and potential geopolitical ramifications.
