From a piece by Hassan Hassan for The Guardian:
Moulhem Droubi, a senior member of the Brotherhood, has said the organisation represents 25% of the Syrian population.
Mr Droubi appears to be a big fat liar. How could an organization that was crushed in 1982 and ruthlessly oppressed for the next 30 years have the presence in Syria to gather such a following? If one day there are elections, it may do well, but but right now the Syrian MB represents a mostly exiled leadership, surely.
The rest of piece is illustrative of the confusion over the opposition.
