The book's approach combines quantitative analysis of military spending with qualitative assessments of political and strategic contexts. Beginning with the historical context since NATO's inception, it progresses through key factors influencing budgetary decisions, case studies of specific European nations, and the impact of alliance agreements like the Wales Pledge. This allows for a nuanced understanding of European defense policy, challenging simplistic narratives about NATO burden-sharing.
By offering a data-driven analysis of European defense spending, the book provides valuable insights for policymakers, military strategists, and anyone interested in the future of European security.
