I think quite clearly, we need to solve the back end to have any form of nuclear power going forward.

Fukushima has reopened the global discussion about the future of nuclear power, but we clearly don't know how this debate will end.

I would imagine there would be, first of all, an extraordinarily strong, and I would imagine, cohesive international pressure, perhaps sanctions, and perhaps a military response.
