The attempt to establish a post-colonial order of kings and strongmen to replace the British and French colonial rule over the Arab Muslim world was doomed from the start. Some of the kings were overthrown by native officers who had been trained by the British and the French to fight their wars. The officers who overthrew them became strongmen themselves.
The recently deposed Ben Ali was a Tunisian officer trained in French and American schools, who had helped push out the French and his predecessor. Egypt's Mubarak was an Air Force officer who replaced Sadat, who replaced Nasser-- all members of the Free Officers Movement which overthrew the Egyptian monarchy.
