Tunisia is a typical case of Arab Spring failure.
Cause number 1 : politic parties after 2011 were all a kind of Mafia, fighting in parliament but sleeping in the same bed behind the curtains.
We have a very corrupted deep state (prior to 2011), that United Medias, political parties, healthy families, syndicates, judicial system, police, football teams presidents, artists, .... To a unique goal of maximum corruption a theft of country ressources.
Our president dissolved the parliament with the full support of the Tunisans but failed to tackle the corruption, he has no political party to assist him, it's almost a "Mission Impossible".
