This New York Times article gives a more realistic assessment of the Muslim brotherhood and why the U.S. should not panic about it. (1) They're not that influential in Egypt; and (2) they forswore violence many years ago. Do I like them? No. Do I agree with them on any issue? Probably not. But too many in the media and maybe in the government are panicking that more Egyptian democracy means that government would be led by the Muslim Brotherhood. An excellent book by an expert on the region is Juan Cole's Engaging the Muslim World. Cole is also a blogger.
