I'm not surprised with Jim's views. He is rather right wing but having said that, whether you are left or right wing, the Nuclear deterrent has worked. However, like most sane people I don't think they are in any way 'desirable' weapons. They are more a necessity given the nutters there are knocking about around the world. The question is are they only relevant for stopping very powerful nations from warring with each other or do they have a wider influence?
His further point about nuclear energy is another difficult issue given the terrible accidents that have happened and continue. Energy security will be a big factor in keeping world peace over the next hundreds of years and Nuclear power has to be in the mix.
We may never achieve the goal of Nuclear Fusion power stations and have free clean cheap energy but until then Nuclear Fission is the next best option. Yes there are serious risks to the local environment with Fission Reactors but so long as they are not the only option and are designed well I don't see how they can be excluded. I do believe strongly that they should be 51% State owned and run as businesses but definitely not foreign owned & run companies, whether French, American or Chinese.
