"Jihad and terrorism carry the same meaning despite the efforts of Muslims to dissociate and differentiate them. Terrorism is not a new phenomenon in Islam, since it has been the main tool for the expansion of Islamic State since Muhammad. Islamic conquests were indeed a form of terrorism, although consistent with the practices of the time. [...] terrorism, the hereditary fruit of Koranic education, has its roots in the East. He is the son of the cohesion policy created by the Prophet Muhammad and his followers, bringing together all pre-Islamic groups under the same ideology: Islam. (pp. 209-210)"
