Don't worry about Japan. It will no longer exist in 50 years. Consider it the new Atlantis. Could go into an explanation why the continuing radiation releases from Fukushima are overwhelming the Island, but that would take too much typing. Just realize that radiation contamination levels in water and soil have been increasing on the island the past year. Everywhere. It cannot be stopped. We do not have the technology to stop the releases. We do not have the technology to adequately clean up the contamination. The Japanese nation just experienced its greatest annual population loss ever. The Chinese will annihilate what remains of Atlantis in a few years.
So now magnify Fukushima by 50 to 100 and you will see what is going to kill most of the planet off. No way to stop that freight train now. We are being led by crony criminal psychopaths.
I think it is more like 1937, after FDR won reelection. He had an economy in depression, failed socialist policies, just like Obama. Four year later we were at war.
