Could crude oil price collapse spell the end of jihad?

It's an interesting thought experiment but the short answer is no.  I for one will not lament lower prices at the gas pump, it's a significant relief that many consumers need - myself included.  Lower oil prices has such a trickle down effect on the price of everything, it's a big win for a beleaguered middle class.  But if I'm in Iraq or Syria and oil prices fall it spells disaster for the economy.  That means more economic hardship and therefore more of an agitated population.  That in turn provides a fertile landscape for ISIS to sew it's seething brand of evil hate.
