Good old Zerohedge.com, has just the right blend of economic doom and unrelenting apocalypse to keep my interest. Its coverage of the build up to World War III, is highly informative, even, entertaining. In a nut shell there are there major developments that could kick the can over the line. These are the Middle East, China and North Korea.

Israel and Iran are already at war, with Israel attacking Iranian military targets within Syria. These were Iran-run bases, attacked by F-35 jets. Iran could retaliate by hitting targets within Israel which will set off the long-awaited Middle East War. Israel could use nuclear weapons if it was felt that there was an existential threat created. So would I if I had them and my flat was under attack, although the paradox is that I would go down in the bang. That would be interesting.
