- ah but that is not entirely true! politicians do know what to do, but it is a tricky path. 》 move away from the Saudis & their cohorts in gulf arab countries. ISIS, AQ, AL Shahab etc are all ideological offshoots of Salafist/Wahhabist nexus. Counter this at the root (financially/ideologically/politically) and almost certain that 90% of the so called islamist extremism would flicker out.
this is going to be a multi year / multi pronged approach, and would need co-ordinated efforts by all kinds of actors (i.e. western + muslim governments, NGOs, religious groups etc). also a stellar idea would be to start giving more support to pluralistic streams of Islam i.e. Sufi, Ismaili, (some of the) Hanafi & like-minded faiths.
