Quizplus · Accepted Answer

Horizontal proliferation refers to an increase in the number of actors possessing nuclear weapons. This can include states that acquire nuclear weapons or non-state actors such as terrorist organizations. An increase in the number of nuclear weapons in the world (choice B) or the number of signatories to arms control agreements (choice C) is not necessarily an example of horizontal proliferation. The spread of control of nuclear weapons to different bureaucracies within a government (choice D) is more related to vertical proliferation.
