The Great Debate UK
Part of the problem trying to figure out what Egypt's Muslim Brotherhood or Tunisia's Ennahda party would do if they got into any future power structure in their countries is knowing what kind of Islamists they are. The label "Islamist" pops up frequently these days, in comments and warnings and (yes) news reports, but the term is so broad that it even covers groups that oppose each other. Just as the Muslim world is not a bloc, the Islamist world is not a bloc.
I sketched out a rough spectrum of Islamists in an analysis today entitled Concern about Islamists masks wide differences. This topic is vast and our story length limits keep the analysis down to the bare bones. But the overall point should be clear that any analysis of what these specific parties might do that ignores their diversity starts off on the wrong foot and risks ending up with the wrong conclusions.
