Hi Caligula,
I'm probably going to disappoint, but I think that the current conflict we are in is simply a continuation of the struggle that began with the birth of Islam in 611 AD.
Islam was expanding from the 7th through 16th centuries, went through a period of reversal and western domination in the 17th through mid-20th centuries, but has once again shaken off foriegn control and is undergoing a period of aggressive expansion once again.
"World War" would seem to imply a relatively quick military conflict between world powers with conflicting political aims. What we are dealing with at present is a continuing struggle against a worldview that aims to supersede and eliminate all other worldviews, and one which cannot be finally resolved by force of arms.
As such, I think it is an entirely different kettle of fish from World War One and Two.
