The primary recruitment tool of ISIS (Islamic State of Iraq and Syria) is social media marketing to appeal to susceptible individuals using heroic narratives. This method allows ISIS to target and attract individuals who may be vulnerable or susceptible to their propaganda.

A key advantage of this method of recruitment is its wide reach and accessibility. Social media platforms enable ISIS to disseminate their message globally and directly target individuals who may be sympathetic to their cause. By using heroic narratives and appealing to individuals' emotions and desire for purpose or belonging, ISIS is able to effectively recruit new members and supporters.

It is important to note that ISIS does not promote or allow the building of systems of government based on democratic principles. Their ideology is rooted in extremist interpretations of Islam and their aim is to establish a totalitarian caliphate governed by their own interpretation of Sharia law.
