Every society has members who feel inadequate in some way. ISIL offers young male sunnis weapons to obtain the power and recognition they crave.
I mention the size of the enemy to point out the absurdity of trying to kill them all.
I do value life but we must value killing the killers more. Otherwise we are nothing more than sheep to the slaughter.
Any messages the West has to offer marginalized sunnis would fall on deaf ears.
Islamic civilization is collapsing. The most talented arabs are leaving arab lands en masse and joining the West. That will be a bumpy merger but it is irreversible and the long term solution to radicalization.
