Praise the Arab Spring, Prepare for the Arab Fall

``No one knows whether what follows the Arab dictatorships will manage to govern the unruly countries that are in the midst of unrest or civil war.

The tyrants, through their secret police, kept the peace. The trouble with the Arab Spring is the Arab Fall. ''
