I apologize. I should have been clearer. I mean that if a group of weapons developers, such as, for instance, the Manhattan Project, discovers certain critical technical data necessary to their weapons, such as, for instance, the critical mass of Pu-239, they will often prefer that these truths not spread to other groups. For as long as they are able to keep this knowledge secret, it is indeed a set of truths that makes this set of weapons designers distinct from other groups.
