The Baltic Bear Trap Wargame, Connor Crookham

Space and Defense

Modern military education increasingly relies on experiential tools that allow students to explore the complexity of contemporary conflict in ways that lectures and readings alone cannot achieve. Nowhere is this more evident than in the emerging emphasis on multi-domain operations, integrated deterrence, and the blurred boundaries between competition and armed conflict. The Baltic Bear Trap wargame was developed as a student design project to meet this instructional need, offering a structured environment in which players must think, plan, and act as operational-level decision makers confronting a deteriorating security situation in the Nordic–Baltic region. Built for use at the Swedish Defense …

A Cislunar Economic Forecast Under Public-Private Partnership, Naisha Chirag Naik

Space and Defense

Cislunar space, spanning Earth’s orbit to the Moon, has emerged as a new frontier due to its strategic, scientific, and economic potential, with growing involvement from global powers, governments, and private entities diversifying the market. Unlike the first lunar space race, which saw a spike in activity amongst two countries followed by “silence,” the current cislunar era is hallmarked by a growing mix of public agencies, private companies, and international actors seeking to gain a foothold in what could be the foundation for a long-term space economy. While cislunar space was historically only an interest for superpowers, recent years have …

Autonomous Navigation In Cislunar Satellites, Heith Johnson

Space and Defense

Cislunar space—the region between Earth’s geosynchronous orbit (about 36,000 kilometers from Earth) and the Moon (roughly 384,000 kilometers away)—is becoming a critical frontier for future space exploration and commercialization.1 This zone includes the Moon’s orbit, transfer orbits, and the Earth-Moon Lagrange points. Additionally, as more nations and corporations launch lunar missions and establish long-term infrastructure, cislunar space is increasingly becoming a strategic focus for exploration, logistics, and transportation.

Planetary Defense As The Ethico-Legal Gateway For International Space Security, Evie Kendal

Space and Defense

Following the news in late 2024 that there was a city-killer asteroid on a possible collision course with Earth, many members of the public were shocked to learn there was no reliable global plan for managing such asteroidal and cometary impact hazards. While calculations of Asteroid 2024 YR4’s trajectory were further refined to exclude the previously reported 2-3% chance of collision in 2032, this event highlighted a major security threat: the lack of a globally coordinated, appropriately resourced, and politically supported planetary defense strategy (Gibney, 2025). In so doing, it also provided an opportunity for security experts to consider the …

Space-Based Missile Defense With Early Interceptor Launch Strategies, William Priedhorsky, James Wells

Space and Defense

There is renewed interest in space-based boost-phase intercept (SBPI) for missile defense against ICBMs of near-peer adversaries. We discuss SBPI in the context of other missile defense approaches, and address one of its challenges, which is the expense of fielding a large enough constellation of interceptors in space to counter even a small number of ICBMs. We develop an early-launch approach that could substantively reduce the required density of interceptors. Because every second matters in boost-phase defense, early launch of interceptors can significantly increase the reach of each interceptor. Early launch would require interceptors that have highly throttleable motors. Our …

Golden Dome: Seeking Space Security, Namrata Goswami

Space and Defense

The “Golden Dome” initiative [formerly Iron Dome] was announced by President Donald Trump on January 27, 2025, signifying a transformative shift in global space security policy. It fundamentally questions long-standing assumptions about deterrence, national vulnerability to missile attacks, and the role of space in strategic defense. More importantly, it emerges at a moment of acute strategic transition: the erosion of Cold War arms control frameworks, the rapid advancement of hypersonic and orbital delivery systems, and the growing integration of space into warfighting doctrines. Launched via a presidential memorandum in January 2025, Golden Dome calls for a layered missile defense system …

When Protection Becomes Predation: Militarized Masculinity And Sexual Violence In Northeastern Nigeria, Tosin Osasona

Dignity: A Journal of Analysis of Exploitation and Violence

The study investigates the structural and situational drivers of conflict-related sexual violence (CRSV) perpetrated by state security actors in the context of Nigeria’s counterinsurgency campaigns in Borno State. Drawing on militarized masculinity and strain and deprivation theories, and using a qualitative, interpretive research design, the study argues that CRSV is not an isolated or episodic form of deviance by individual soldiers and security personnel but is embedded in routine military–civilian interactions. Advancing an interactionist explanation of CRSV in Nigeria’s Islamist counterinsurgency operations, the study demonstrates that the likelihood of sexual violence increases through the interaction of gendered institutional norms, operational …

Book Review: Overseen Or Overlooked? Legislators, Armed Forces, And Democratic Accountability, Tom Vance

Parameters Bookshelf – Online Book Reviews

Authors: David P. Auerswald, Philippe Lagassé, and Stephen M. Saideman

Reviewed by: Tom Vance, US Army Reserve (retired)

In Overseen or Overlooked?, David P. Auerswald, Philippe Lagassé, and Stephen M. Saideman challenge the conventional focus on executive control of the military by spotlighting the often-underestimated role of legislatures in democratic civil-military relations. Drawing on more than a dozen global case studies, the authors reveal how parliaments struggle with capacity and motivation to provide meaningful oversight. This groundbreaking work offers practical reforms and a compelling argument: true democratic accountability in defense requires more than generals and presidents—it demands empowered legislators.

The Impact Of Japan’S Security Policy Expansion On Great Power Competition In Southeast Asia: The Case Of Indonesia, Rafyoga Jehan Pratama Irsadanar

Global: Jurnal Politik Internasional

This paper discusses how fragmented perceptions of threat impact the outcome of international security cooperation. It analyses the impacts of Japan’s expanding security posture in Southeast Asia, specifically focusing on the Japan-China great power rivalry in the region. While previous research has examined Japan’s intention to intensify its security engagement with Southeast Asian countries, this paper aims to study the broader impact of Japan’s expanding security cooperation on the region's security constellation. To achieve this objective, the paper employs Japan-Indonesia security and defence cooperation as a case study. The research found that, despite strengthening bilateral relations, the increasing Japan-Indonesia security …

Protecting America’S Critical Infrastructure: A Shared Responsibility In An Era Of Escalating Cyber Threats, Alan Saquella

Publications

The recent cyberattacks targeting municipal water facilities across multiple U.S. states serve as another reminder that America’s critical infrastructure remains under constant attack. According to the FBI, Environmental Protection Agency (EPA), and the Cybersecurity and Infrastructure Security Agency (CISA), attackers successfully compromised operational technology (OT) devices, including programmable logic controllers (PLCs), by exploiting Internet-connected systems, changing administrator credentials, and disrupting normal operations. Fortunately, local operators responded quickly by isolating affected systems, restoring backups, and preventing what could have become a significant public health crisis.

While these incidents focused on water treatment facilities, they represent a much larger national security issue. …

System Leadership For Sdg-Aligned Research Security In Ireland, Seán Lacey

Publications

What is new?

Research security has rapidly emerged as a priority in research governance across Europe and internationally. However, discussions frequently frame research security primarily in terms of national security or geopolitical risk, with limited attention to how security measures intersect with sustainable development objectives. This paper addresses this gap by exploring the relationship between research security and the Sustainable Development Goals (SDGs), using the emerging Irish research security framework as an illustrative context. It argues that research security and sustainable development are not inherently in conflict; however, aligning them requires coordinated system leadership to ensure that security measures protect …

Cooperation In The Space Domain: The Potential For Cooperation Between South Korea And Japan, Brianna Johnson

Discovery Day - Daytona Beach

This project examines the space security cooperation between two states that are frequently grouped together in discussions of U.S. allies in the Asian region, largely due to the trilateral alliance between the US, South Korea, and Japan. Within this framework, particular attention is given to what some scholars identify as the “weak link” of the alliance: the relationship between South Korea and Japan. Focusing on the space domain as an emerging area of strategic importance, this paper asks when and how states with historically tense relationships engage with one another in space. Drawing on primary news sources and government documents …

Measuring Intensity Of Carrier Strike Group Anti-Air Warfare: 1945-2025, Gavin Perry

Discovery Day - Daytona Beach

The Aircraft carrier and its associated strike group (CSG) have been the preeminent means of both projecting power and securing sea control since the 1940s. Despite this, there exists vulnerabilities associated with operating these groups. Following World War Two, a narrative emerged that in heavily contested (non-permissive) environments, CSGs would be unable to operate effectively. This line of thinking relegates the CSG to a weapon for low intensity conflicts, crisis response, and peacetime power projection. The relevance of this debate has increased in recent years with the bolstering of the Peoples Liberation Army Navy (PLAN) carrier forces. Misunderstanding the ability …

A Nuclear Crossroads: South Korea's Nuclear Stance And The Factors That Shape It, Brianna Johnshon

Discovery Day - Daytona Beach

South Korea represents a standard case of latent nuclear power, where nuclear development is constrained by choice rather than capability. In the past, Seoul’s rhetoric surrounding nuclear capabilities has ranged from endorsement of a domestic nuclear program to a staunch commitment to nonproliferation. These shifts are shaped by both foreign and domestic factors that reflect Seoul’s broader strategic calculations. Through comparative case studies of three key periods in South Korea’s nuclear rhetoric, this paper analyzes the main factors that influence the official stance on nuclear development. The first case covers early attempts at nuclear development in the 1970s with Project …

Perceiving A Competitor: Culture And Cognitive Biases Of The Strong Enemy And The Pacing Threat, Allison Abbe

Books, Monographs & Collaborative Studies

The United States and China are prone to systematic cognitive and cultural biases that distort their mutual perceptions. Addressing these biases through cultural education and professional development is essential to overcoming blind spots in understanding the United States’ primary competitor. By applying dynamic constructivist theories from cross-cultural psychology to national security, this monograph builds on existing scholarship to reveal specific cognitive asymmetries between Western and East Asian observers. Differences such as holism, dialecticism, social inference, and perspective taking reflect the cultural lenses through which security actors perceive their competitors’ actions and intentions, but US observers often overlook the cultural factors …

Fighting With Data: Design Implications For Ai-Enabled Mission-Command Systems, C. Anthony Pfaff

Books, Monographs & Collaborative Studies

Fighting with Data examines how artificial intelligence (AI) is reshaping military decision making by changing both the speed of command and the structure of cognition within mission-command systems. Rather than treating AI as a tool that merely accelerates existing staff processes, this monograph recognizes AI redistributes cognitive labor across a network of people, data, tools, and operational processes. In this new environment, commanders and staffs spend less time assembling information and more time interpreting meaning, judging uncertainty, and deciding how to act.

This shift in the human role requires a new way of thinking about trust in military AI. Traditional …
