Climate Change As A Dangerous Accelerant Of Mass Atrocity, Jesse Jenkins

Space and Defense

Student Voices

Investigating potential connections between mass atrocity and climate change reveals that the vulnerability of food systems may be valuable predictive factor in understanding which states will respond to climate change with violence.

An ongoing study by Dr. John Riley and Lt Col. William Atkins shows that strong states tend to be able to cope well with the effects of climate change and not turn to violence. They also argue that the weakest states are already broken and on the path of committing a mass atrocity regardless of the effects of climate change. This leave a middle section of …

No Method To Madness: The Failures Of Madman Diplomacy In All Its Forms, Henry Gilchrist

Space and Defense

Student Voices

Madman diplomacy fails to work as advertised. Internal contradiction of the strategy in it s ideal form reduce the chances it will succeed in future crises.

Effective deterrence requires an actor to pair powerful capabilities with a believable will to use them. The world of United States' dominance has relegated the question of will to the periphery. However, the U.S. is emerging from its hegemony with enough self-awareness to acknowledge the painful consequences of this relegation. Democratic restraint has historically played an important role in nuclear deterrence for obvious reasons, and the issue of will deficit is not …

Boosting Space Diplomacy At State, David A. Epstein

Space and Defense

Notes from the Field:

Space diplomacy remains an esoteric specialty of State.

With ever-increasing speed, humanity is expanding the scope of its activities in outer space, thanks to private enterprise as well as via national pursuits. In the last two years alone, for example, the number of active and defunct satellites in lower Earth orbit has increase by more than 50 percent, to around 5,000, with plans to add tens of thousands more in the coming years. Equally surprising, these satellites are owned and operated by nearly 100 difference countries and organizations around the world - no just the small …

Future Directions For Great Power Nuclear Arms Control, T. Justin Bronder

Space and Defense

Extending the current New START regime can help maintain traditional strategic stability; however, such an approach fails to address destabilizing trends related to non-nuclear strategic technologies and China's expanding forces.

Arms control in the nuclear age has proved a useful tool of national security, meeting ends as diverse as reducing the risks of nuclear war to channeling strategic competition. Yet recent trends indicate arms control may be at an inflection point; the suitability of this tool in general and the viability of securing new agreements specifically are both unclear. The New Strategic Arms reduction Treaty (New START) extension somewhat reverses …

Student Contribution.

Cyberspace refers to a purely virtual arena that has become increasingly relevant in the past few years, as countries develop more cyber weapons and carry out more cyber attacks. The cyber domain has a large scope because of its virtual nature, and it has a high potential threat level as the full impact of cyber capabilities are not even understood yet. As the possibilities for destructive cyber weapons are virtually endless, the threats are also virtually endless. Because of the growing relevance of cyberspace and the high danger level, deterrence thresholds are a pressing issue in this domain. …

Us Blindness To Russian, Chinese Cultural Motives Risks Nuclear Escalation And Ill-Fit Response, Ryan C. Bushman

Space and Defense

Student Contribution.

This paper was authored prior to the 2022 Russian invasion of Ukraine and the publication of the 2022 Nuclear Posture Review.

The United States has taken numerous miscalculated steps with respect to foreign and nuclear policy based on an incomplete understanding of the motives of both China and Russia. This is, in part, due to a failure to acknowledge these nations' strategic culture - an enduring system of values that influence a nation's use of military force. As the US is about to put forth its 2022 Nuclear Posture Review (NPR), it is critical that future responses to …
