imo oil is a manifestation of the real issue here, which is the future of america(and the world at large). the us needs to secure resources to
a) maintain its oil dependant way of life through the transition to cellulose technology(my guess as the heir apparent, not fact)
b) mitigate the growth of china
iran, iraq and north korea seem more like smokescreens than threats to me, the real threat is 1.25 billion chinamen who decide its their time to shine.
