I can locate my previous papers and dissertation project as part of security studies, especially in alliance politics and extended deterrence. In my dissertation project, I will closely examine the unanswered questions in alliance politics: when do alliance member states fulfil peacetime military commitments? How can a patron’s peacetime alliance military commitments influence the protégée’s decision to initiate militarized disputes? To answer these research questions, I collected an original dataset to examine peacetime military commitments – patron’s actions taken after the signing of the alliance treaty. My project reveals that alliance peacetime commitments are strong signals of alliance credibility. This investigation into alliance commitments is essential to enhance our understanding of alliance dynamics and inform policy decisions in managing existing allies.
