Nope ... no WWIII.
We are too "well-informed" in this enlightened age of communication. We see all, and fear all, and get very pessimistic. The media gets us into a frenzy through sensationailism, reporting anything that hits a nerve.
If such an instantaneous news service existed during WWI and WWII, can you imagine what would have been thought?
"Nix Negativity" - stop watching, or believing CNN.
Oh, yes, we have a few countries in a real fine mess, Ollie, but our history has shown that we have always had global hotspots.
N. Korea - they are playing the shell game and poker at the same time. They want financial aid "without strings". A great game of bluff.
China - like Russia did, realizes that in our world of instant communication, they can no longer easily suppress their people. It is a costly process and they want a big piece of the global $$ - called capitalism. They will become an even bigger player in that area.
The Middle East has always been a "trouble" area - read your history, and long before anything but eskimos and aboriginals ran around North America.
Russia is still a bankrupt mess, and will be for some time to come. Slowly trying to merge into the global economy, after neglecting the obvious for so long.
WWIII won't be allowed to happen.
