text_A: In each country with an MB there is a Branch committee with a Masul (leader) appointed by the General Executive leadership with essentially the same Branch-divisions as the Executive office. "Properly speaking" Brotherhood branches exist only in Arab countries of the Middle East where they are "in theory" subordinate to the Egyptian General Guide. Beyond that the Brotherhood sponsors national organizations in countries like Tunisia ("Ennahda Movement"), Morocco (Justice and Charity party), Algeria (Movement of Society for Peace). Outside the Arab world it also has influence, with former President of Afghanistan, Burhanuddin Rabbani, having adopted MB ideas during his studies at Al-Azhar University, and many similarities between mujahideen groups in Afghanistan and Arab MBs. Angkatan Belia Islam Malaysia in Malaysia is close to the Brotherhood. According to scholar Olivier Roy, as of 1994 "an international agency" of the Brotherhood "assures the cooperation of the ensemble" of its national organizations. The agency's "composition is not well known, but the Egyptians maintain a dominant position".
text_B: If this passage was all that you knew about this agency, would it still feel like a safe bet to say that Egypt will stay in their current position even after The United States has a new president, or the UN has a new secretary general?
YES.
