> why was there this idea that burying waste now was a good idea?
I've already answered that: nobody actually thought it was a good idea. It was imposed as a policy because the actual (though of course not publicly admitted) purpose of the policy was to kill nuclear power by imposing unreasonable requirements on it. (It's possible, I suppose, that the Cold War rationale you give played a role, but I don't think it's very likely; that objective could have been met without requiring anything like 100,000 year storage.)
First, it may have been thought that opposition to nuclear energy is due to waste, and that burying it would remove the opposition. I consider this ill-founded, both because those predisposed to oppose nuclear use waste only as one of many arguments, and because the actual objective argument (economics) as nothing to do with waste.
Second, it may have been thought in the height of the Cold War that spent fuel at the surface would be a tempting target for ground burst H-bombs, where it would then contribute to long term fallout (each 1 GW(e)-year of spent fuel has about the same long lived fission products as a 20 MT bomb.) This is not an argument the government would have been pushing publicly, of course.
