What I really, really do not get is why the countries that do have long term solution do not start selling nuclear waste disposal services to other countries.

What I really, really do not get is why the countries that do have long term solution do not start selling nuclear waste disposal services to other countries. First, you could charge outrageus amounts of money for the service. Second, you could practically ditch your defence forces simply because absolutely nobody would want anyone else to attack a country with huge amounts of radioactive waste. Finally, after some time, you could likely sell the waste back as a fuel ingredient to new nuclear technologies. This only slightly tongue in cheek. Of course I understand that proposing that would be a political suicide, but nevertheless, it would make sense.
