This is the purposeful plan of violence that Abu Bakr al-Baghdadi, the Islamic State’s self-anointed Caliph, outlined in his call for ‘volcanoes of jihad’: to create a globe-spanning jihadi archipelago that will eventually unite to destroy the present world and create a new-old world of universal justice and peace under the Prophet’s banner. A key tactic in this strategy is to inspire sympathisers abroad to violence: do what you can, with whatever you have, wherever you are, whenever possible.
