It's incumbent upon citizens to do what we can to prevent the horrors of the deployment of nuclear weapons. All humanity, all living creatures, our entire planet are at stake. The Kings Bay Plowshares activists were trying to educate people to the dangers of nuclear weapons, and, in so doing, bring us one step closer till these weapons are abolished.
The people who profit from the building of these weapons are the criminals, not the people who alert us to the problem. Nuclear weapons are weapons of mass destruction. To even produce them is a crime against humanity.
