>> His only major failure has been in Egypt ?
Context is everything.
The statement refers to his advancement of the Sunni cause in general. In that area, Obama has been quite successful. But not in Egypt.
Egypt became a major exception when the Egyptian people rose up and threw out the Muslim Brotherhood. That has to be viewed by our Sunni President as a major failure. In Iraq, the Sunni's are on the rise. Ditto in Libya and Syria. Afghanistan is next.
