Just read some first-hand on-the-ground email from Japan, which I don't have permission to quote, but which can be usefully summarized. The key point is that, whatever you see on CNN, a lot of Japan is actually something like close to normal. Tokyo is open for business as for the heavily populated industrial heartland to the south; also (more of a surprise to me) the far north island of Hokkaido. They're having aftershocks and they're being told they will face rolling power outages but (another surprise?) they haven't started yet.
And the nukes--boy, the nukes. Still too early to guess how that will play out. I grant that my first thought was--oboy, as a political program, nuclear power is dead. Well, maybe. I can't really blame the networks for showcasing nukes over the weekend; nobody wants to underestimate the threat of a nuclear disaster. But if it turns out that the Japanese somehow dodged a plutonium bullet here, I wonder if maybe nukes will come charging back stronger than ever. Like the stock market "crash" of 1987 which taught a generation of traders that market busts don't matter (sarcasm).
Update to update: well, you pays your money .... link.
