History is too sensitive to be treated arbitrarily when one is addressing a schism that dates back 1400 years and is at the heart of the modern day clash of ideologies. To my taste Obama should have done some more homework. He has left of lot of ammunition in the hands of those who thrive on logic of moral equivalence and demand political causes of what makes an individual a suicide bomber.
When President Obama spoke to the Muslim world in Cairo, a large portion of his guests were leaders and members of the Muslim Brotherhood. The speech was designed to please them more than supporting the reformist movement in Egypt and across the Muslim world.
Obama's overgeneralizations are a dangerous precedent: Algebras and magnetic compass plus paper came from cross fertilization of Islamic societies with the sub-continent and China. An American president has to be careful with reference to history. Giving credits of accomplishments without highlighting the cause will further add to moans and groans of a society that fails to understand the reason of its continual decline in the field of intellect for last 1000 years.
The Obama administration had hired the first White House Muslim advisor, Dalia Mogahed, who helped with writing Obama's speech. Mogahed is herself an Islamic ideologue who supports Islamic Sharia and denies any connection between radical Islam and terrorism. Mogahed, who was born in Egypt, has also been a firm defender of the Council on American-Islamic Relations (CAIR) and the Islamic Society of North America (ISNA). Both of these US groups are tied to the Muslim Brotherhood.
