Here in North America, the IB is virtually unknown. Well, the Brookings Institute's Saban Center for Middle East Policy has an article you should read, "Don't Fear Egypt's Muslim Brotherhood", by Bruce Riedel. The site has other articles worthy of your perusal, too.
The prospect of change in Egypt inevitably raises questions about the oldest and strongest opposition movement in the country, the Muslim Brotherhood, also known as Ikhwan. Can America work with an Egypt where the Ikhwan is part of a transition or even a new government?
The short answer is it is not our decision to make. Egyptians will decide the outcome, not Washington. We should not try to pick Egyptians' rulers. Every time we have done so, from Vietnam’s generals to Afghanistan’s Hamid Karzai, we have had buyer’s remorse. But our interests are very much involved so we have a great stake in the outcome. Understanding the Brotherhood is vital to understanding our options.
The Muslim Brethren was founded in 1928 by Shaykh Hassan al Banna as an Islamic alternative to weak secular nationalist parties that failed to secure Egypt’s freedom from British colonialism after World War I. Banna preached a fundamentalist Islamism and advocated the creation of an Islamic Egypt, but he was also open to importing techniques of political organization and propaganda from Europe that rapidly made the Brotherhood a fixture in Egyptian politics.
