Why is Tunisia producing so many terrorists?

Tunisia is a liberal country, compared to other Middle East and North Africa Muslim countries. Why then is it producing so many terrorists? Tunisia has only 11 million people, but 7,000 Tunisians joined ISIS fighters, more than Saudi Arabia and Egypt, which have a combined population of over 112 million people.
The reasons include the fact that the 2011 revolution that toppled the dictatorship and the democratic institutions that followed actually gave jihadists greater freedoms to organize, travel, and share information. The unemployment rate is high, over 30% for young people, which also promotes a feeling of hopelessness also propels the youth into jihad.
