Regime change refers to the process of replacing one government or political system with another. This can occur through various means, including military intervention, popular uprisings, or diplomatic efforts. The goal is often to establish a new leadership that aligns more closely with certain political, economic, or social ideals. Historically, regime change has been a significant aspect of international relations, with examples such as the Iraq War in 2003, where the United States sought to remove Saddam Hussein from power. While some view regime change as a means to promote democracy, others criticize it for leading to instability and conflict.
