The Washington Post has a plausible discussion of what ties together the bizarre list of Islamic organizations designated as terrorist groups by the United Arab Emirates. The Council on American Islamic Relations designation is attracting particular attention.
One possibility that is complementary to the Post's emphasis on Muslim Brotherhood connections: the government may have hired a consulting firm to assemble the list for them, and whether through the incompetence of the consultants or them not being told what the purpose of the list was, they did a search engine sweep of groups that get mentioned -- by anyone! -- in the context of Islamic extremism. They got the cheque, and Abu Dhabi got the list. This is the government that has an American consulting firm -- the Camstoll Group -- on a specific assignment to bash Qatar.
