Abstract

We describe a multi-country, multi-stakeholder model for the accrual and use of nuclear weapons and illustrate the model's value for addressing nuclear weapon proliferation issues using an historic Pacific Rim scenario. We instantiate the agent-based dynamic-network model for information and belief diffusion using data from subject matter experts and data mined from open source news documents. We present the techniques that supported model instantiation. A key feature of this model and these techniques is enabling rapid model reuse through the ability to instantiate at two levels: generically and for specific cases. We demonstrate these generic and specific cases using a scenario regarding North Korea's interest in nuclear weapons and the resulting impact on the Pacific Rim circa 2014that is, prior to the fourth and fifth nuclear weapons test by the Democratic People's Republic of Korea. A key feature of this model is that it uses two levels of network interactioncountry level and stakeholder levelthus supporting the inclusion of non-state actors and the assessment of complex scenarios. Using this model, we conducted virtual experiments in which we assessed the impact of alternative courses of action on the overall force posture and desire to develop and use nuclear weapons.
