A number of nuclear weapons issues (renewing the non-proliferation treaty, curbing global proliferation, spending vast sums on making and maintaining nukes) are becoming hotter. We can't seem to escape their lethal embrace.
Why haven't we rid humankind of nuclear weapons? These are the weapons that can end the grand evolutionary experiment (or God's handiwork, if you like) that we call humanity. We conceived of them, devoted human and material and financial resources to research and invent and build and use them, and they are clearly impossible without the human mind and human hands. We have constructed a massive species-suicide arsenal, still threatening humankind with almost 24,000 of these weapons, and not only refuse to give it up, we are proliferating it. Why? There are many reasons, including the following, all of which need to be addressed.
The nations with nukes are clever and those without them are wise. This is a long, tough process. Better start right now.
