Feedback: World War 3?

This is an interesting question. Do you think there is possibility of a WW3 in my life time? First of, Ill start by looking at the stats.

There was a "chain of events" that lead to both previous world wars. First off, alliances were made, and broken. Land was unrightfully taken or conquered, and high ranking figures were assassinated. Look at whats happening today! 9/11, Saddam Hussiens Reign, US occupation of Iraq, The Conflict between Gorgia and Russia etc. There is already much unrest in the world, the perfect conditions for a war (not to mention Civil War in African Countries, and the Diamond Crisis, and jihad seeking factions in the middle east). But, in reality, I actually feel there is more chance still, of there NOT bieng a World War 3. The world has already seen 2 devastating world wars, and they've always been between two main powers. The World as it is today, i feel does not have two majour super powers that could be strong enough to engulf the land into chaos. Then again, a new kind of war can start. Instead of 2 huge allied powers against another, there could be multiple. This in my opinion could be much worse. But, again contradicting what i said, anything can happen in a lifetime. See where technology has gotten in a mere 20 years. There is nuclear power, weapons of mass destruction, etc. God knows what crazy new warmachine could spawn...

I think that if im wrong, and that there actually will be a WWIII, that it'll be another Cold War...only more voilent. I think that the majour cause of conflict these days is a clash of ideologies. Were seeing it now in the middle east, and africa. Another possible cause may be oil...when it gets super super super uber uber scarce.
