How to face ISIS?
The war in Syria and Iraq is now turning against ISIS so they will start focussing their arms and capital towards potential soft targets because they know it will have a significant impact.
The military part of ISIS will have to be solved like any other army: physical removal, meaning bombing and shooting the hem out of existence.
Afterwards you install a stable leader in the area: for syria this is assad and for Iraq this is not clear yet.
The terroristic part of ISIS must be fought by counter-terroristic activities, protecting the civilians (military deployment on the streets and heavier arming of police officers) and talking with the islamic community since there is a proven problem with Islam.
