The Muslim Brotherhood, or Ikhwan, has engaged in terrorism, assassinations, and anti-Western, anti-Semitic rhetoric and violence for almost a century, yet few Americans realize how powerful they really are. While we focus on al Qaeda, Hamas, and Hezbollah, it is actually the Muslim Brotherhood, the world's oldest, most influential, and most anti-American Islamist group, that has become the preeminent voice and power in the Muslim world. Hiding behind a cloak of respectability and expensive Western suits, the Muslim Brotherhood is installing vehemently anti-American government.
