Ahh, cactus dome...where the surrounding area is more contaminated than the actual contents under the concrete. A sad, and undeniable side effect of the advancement of our understanding of fission and fusion at a time where a ruthless future belligerent was in a race at any cost with us to harness the technology. I'm not saying it's ethical, but now that it's been done, we have a significantly greater understanding of nuclear physics, which will undoubtedly greatly help future generations in harnessing the power in a safe, peaceful, manner.
My stance on nuclear technology is this: as with most technological advances in modern history, they mostly derive from military endeavors; thusly, nuclear power generation being an offshoot of nuclear weapon development, it is our duty to stay at the forefront of nuclear technology, both militarily as well as civilian, as to keep advanced ahead of any current or future users who may use the technology for evil. I.E. now that the dragon is out of the box, we must be the caretakers of it.
It's not the world I would have created, but now that we're here, it's the stance I must take...
