Connectedness And Belonging: An Autoethnography About Military Veteran Transition, Benjamin A. Smet

USF Tampa Graduate Theses and Dissertations

Military veterans often face profound challenges transitioning to civilian life, yet prevailing narratives focus narrowly on PTSD and combat trauma. This dissertation uses autoethnography to broaden that view, blending personal narrative with theory to explore seven interrelated transition stressors: grief and bereavement, loss of military identity, autobiographical memory, service-connected nostalgia, moral injury, stereotype threat, and socialized masculinity and stoicism. These layered stories illuminate the cultural, emotional, and relational dimensions of transition, showing how isolation, disconnection, and loss of belonging shape veteran experiences as deeply as trauma. The analysis demonstrates that healing emerges not from prescriptive programs but from relational practices …

Intelligence As An Instrument Of National Power: Lessons Learned From The Tensions Between Serbia And Kosovo, Vadym Chernysh

Journal of Strategic Security

Intelligence activity is unique; it can be a valuable and powerful tool in the hands of state leaders. Leaders should rely not solely on their perception or intuition to leverage the intelligence instrument of national power but rather on understanding this phenomenon and its inherent qualities. Often, political leadership may confuse the functions of intelligence and law-enforcement agencies, leading to the ineffective or inefficient use of national power instruments to achieve strategic goals. Leveraging the intelligence instrument of national power in prolonged conflicts with a larger adversary is a crucial aspect of statecraft. The role of intelligence can be vital …

The Institutional Effect: Democracies, Dictators And Diversionary Foreign Policy, Thomas Reilly

Journal of Strategic Security

The diversionary theory of war remains controversial in International Relations. The extant literature remains dominated by the study of democratic diversions and the use of warfare as the prime diversionary strategy. The sheer amount of work covering democratic diversions has created theoretical biases which are oft transposed to autocratic states, despite being largely unique to democratic processes. This article expands the traditional bounds of diversionary theory to provide a logic of autocratic diversions and diversionary strategies outside of war, presenting a theoretical framework which argues that institutionalization is the primary conduit through which the intended audience, benefit and preferred diversions …
