Neoconservatism is a political ideology that emerged in the United States during the late 20th century. It advocates for a proactive foreign policy, emphasizing the promotion of democracy and American values abroad. Neoconservatives often support military intervention as a means to achieve these goals, believing that a strong national defense is essential for global stability. The movement gained prominence in the 1980s and 1990s, particularly under the presidency of Ronald Reagan. Key figures include Paul Wolfowitz and Donald Rumsfeld, who played significant roles in shaping U.S. foreign policy, especially during the Iraq War in the early 2000s.
