First Lucky Island
If you are a fan of nuclear energy, that one thing is that even after one of the biggest earthquakes ever followed by a huge tsunami, the worst case scenario didn't happen. Nuclear is even more good-to-go than before.
If you are a nuclear foe, then what happened in Japan proves how dangerous this technology is. It is only pure luck and seat-of-the-pants management that prevented a complete meltdown and huge nuclear disaster.
I look at things differently.
