High Ability, Hidden Gaps: Building Quantitative Reasoning Amongst Singapore’S Mathematically Literate, Rebecca M. Nichols

Numeracy

In Singapore, where primary and secondary students routinely top standardized worldwide mathematics examinations, a paradox emerges: when reaching university, many struggle to apply their skills critically in real-world contexts. This commentary examines the challenges and strategies involved in teaching quantitative reasoning (QR) to mathematically literate students in a top-ranking Singaporean university. While these students arrive well-trained in computation and procedural problem-solving, they often lack confidence and flexibility in ambiguous, data-driven decision-making. This article argues that fostering QR education is crucial not only for Singapore but for education globally, as QR skills underpin evidence-based reasoning within and across disciplines. Such an …

Gnsi Decision Brief: De Oppresso Liber – Applying Green Beret Identify And Ethos To Build U.S. Military Resiliency, Robert S. Burrell, Joseph E. Long, Charles Cleveland

GNSI Decision Briefs

Military ethos is the “spirit of the unit, which is the sense of unity that leads warriors on the battlefield to believe that the lives of those around them are more important than their own.” In 2025 Secretary of Defense Pete Hegseth promised a return to a “warrior ethos,” which he said the Department of Defense (DOD) has lost because of the recent politicized climate, including diversity, equity, and inclusion policies. This brief will utilize the Army's Special Forces as a viable model for achieving collective military spirit in one of the world's most diverse nations.

Understanding The Strategic Value Of The Assassination Of President Juvénal Habyarimana, Jonathan R. Beloff

Journal of Strategic Security

This article examines the assassination of former Rwandan President Juvénal Habyarimana through the utilization of strategic theory. The President's assassination on the night of April 6, 1994, ignited the 1994 Genocide against the Tutsi, which killed up to a million Rwandan Tutsis and non-extremist Hutus within 100 days. While the assassins are still unknown, speculation exists of whether the Rwandan Patriotic Front (RPF) or the former ruling akazu ordered the attack. It concludes that the akazu was the most likely actor behind Habyarimana's assassination, given that the structure of strategic incentives favored its position over the alternatives.

Communicating Assessments With Impact: Insights From The Scientific Community, Emily M. Mccarthy

Journal of Strategic Security

Assessments analysts are extensively trained in the application of analytic techniques, but less time is spent equipping them with the tools needed to communicate their assessments effectively. Great pains can be taken to frame, research, and answer an assessment question, but that effort is wasted if the message isn’t heard and embraced by decision makers. An analogous challenge is experienced in the scientific community, where researchers are traditionally trained in methodological rigor rather than impactful communication. Acknowledging this, the scientific community has undertaken a concerted effort to develop and implement evidence-based strategies to communicate its findings with impact. This article …

The Impact Of Small-Scale Conflicts On Post-Soviet Alliances, Ani Hakobyan

Journal of Strategic Security

Military alliances are crucial for international and regional security. However, conflicts may disrupt these connections, weakening alliance structures, particularly in complex regions such as the post-Soviet space. This article examines the effects of small-scale conflicts on the post-Soviet alliance network by analyzing the impact of three conflicts: the 2008 Russo-Georgian War, Russia's 2014 annexation of Crimea, and the 2020 Nagorno-Karabakh (Artsakh) War. Using the temporal exponential random graph model (TERGM), the study finds that three conflicts significantly weakened alliance structures in the region, reducing the likelihood of new alliance ties within both the Collective Security Treaty Organization (CSTO) and broader …

Rethinking Cyber Deterrence: Adapting To The Realities Of The Digital Battlefield, Peter Pijpers, Kraesten Arnold

Journal of Strategic Security

The question of whether deterrence is achievable in or through cyberspace has sparked considerable debate among academics. Over time, arguments have evolved, further entrenching this discourse and moving it out of the mainstream spotlight. This article examines how recent armed conflicts in Ukraine and Gaza may reinvigorate discussions surrounding this issue. It emphasizes that cyber activities can indeed produce deterrent effects while also recognizing the necessity for a new terminology to accurately capture these effects. In cyberspace, traditional deterrent logics—such as deterrence by denial or punishment—along with core principles including credibility, communication, and cost-benefit analysis, do not uniformly apply due …

American Extremism: An Evolutionary Process, Christopher Young, Michael Damian Tucker

Journal of Strategic Security

This article critically examines the historical definitions of American right-wing extremism as utilized by the media, political community, academia, and the government. We suggest that the historical definitions of the right wing are inadequate and fail to describe extremism accurately and consistently. Using evolutionary game theory, this article further argues that right-wing extremism (and left wing) is based on an evolutionary process to secure social existence and will rise as predators challenge historical hierarchical systems.
