Military withdrawal refers to the process of a country's armed forces pulling out from a specific area or conflict zone. This can occur after a peace agreement, a change in strategy, or the completion of a mission. The goal is often to reduce military presence and allow local governments or forces to take over security responsibilities. The decision to withdraw can be influenced by various factors, including political pressure, public opinion, and the effectiveness of local forces. For example, the withdrawal of U.S. troops from Afghanistan in 2021 marked the end of a long military engagement and raised questions about the future stability of the region.
