The world is busting it's seams with new consumers wanting to use it. Unfortunately, the big guys (and a few wars) have used up most of the cheaper stuff, now the developing world wants a bigger piece of the action. Add to this some barbarians who desire to dominate the energy-rich regions, and use a phony religious-based jihad to accomplish their goals, and we have the first two items in the subject line.
What about the third item?
A "war on terrorism" is a great tool for dictators. Remember how "Big Brother" in Orwell's book 1984 (is it really that long ago?), kept his control through having a state of perpetual war.
Is it possible that Russia and the United States now have a two-headed "big brother" by the name of BushPutin?
