It must be absolutely irresistible for a politician to scrap an existing plan for a nuclear waste dump. With one photographic sweep of the hand he is guaranteed to garner a handful of votes. I fear this will go on ad infinitum.
So, what if the next bunch of blue ribbons picks North Dakota? Well, we'll cancel that at the next election! Then we'll just gather more ribbons to make another choice. We can't diss nuclear, no sirree, that'll cost votes!
So, Australia and the US are in a contest on who will be able to cancel the most sites. Maybe other countries will join?
