According to this article, MB in Egypt is a hybrid of both:
"Egypt's Muslim Brotherhood (MB) has recently shifted its political position and aligned with Iran. Historically, the MB, as an extremist Sunni movement, had anti-Shiite sentiments. However, this new “unholy alliance” is based on common political interests. Iran, having hegemonic ambitions, launched a cold war against the Arab countries, including Egypt. Hence, the MB, which wants to take over Egypt, is interested in supporting Shiite Iran. However, this new political shift, created a major rift inside the MB."
Thank you all. It sounds like the answer could be that the MB is Shia, or at least leans that direction. This would fit in with my theory that Obama, for whatever reason, seeks to consistently raise Shia interests and seeks to destroy Sunni power.
Two big surprises about Obama are his escalation in ‘Stan and his holding of the Bush course in Iraq. At first I thought reality had intruded once he got in office. Maybe that’s not the answer.
This would explain his expansion of the drone attacks against the Sunnis, and his silence regarding the resistance in Iran to the Shia leadership there.
Exit question:
Has Obama taken sides within the Islamic movement, and has he taken the side of the Shia?
