Abstract

This chapter examines the transformations in warfare, power dynamics, and international relations in the 21st century, focusing on redefining concepts such as superpower, battlefield, war, and army. Using structuralism and post-structuralism frameworks, the research analyzes recent conflicts, including the Russia-Ukraine war (2022-2024), Hamas's October 7, 2023 attack on Israel, the Israel-Gaza conflict (2023-2024), and Iran's Proxies vs. Israel (2023-2024) as critical case studies. Key findings reveal a significant shift in modern and post-modern conflict. Traditional definitions of superpower are challenged by countries like Iran, which exert influence through proxy networks and asymmetric warfare. Battlefields now span physical, cyber, and informational domains simultaneously. The concept of war has evolved to include complex, multi-actor scenarios involving both state and non-state entities, with groups like Hamas (and Hezbollah) demonstrating capabilities traditionally associated with state armies. The research highlights the role of technological disruption.
