Defense Dominance Reshapes Global Power Dynamics
Recent conflicts, including Russia's invasion of Ukraine and the U.S. war with Iran, suggest a shift toward defense dominance, where weaker states can effectively defend against stronger powers using drones and missiles. UN Secretary-General António Guterres noted that superpowers' ability to impose their will has been severely limited. This changes the calculus of military power and international relations.
The article highlights how technological advances in drones, precision missiles, and surveillance systems have eroded the traditional advantages of larger military powers. These tools allow smaller states to defend territory effectively and strike at distance, while costly assets like aircraft carriers and stealth aircraft become increasingly vulnerable to cheaper defensive systems.
The shift toward defense dominance challenges long-held assumptions about military intervention and coercion. The United States, accustomed to projecting force with relative impunity, now faces adversaries equipped to impose significant costs. Historical precedents, including the Vietnam War, already demonstrated limits to superpower military might against determined local resistance.
This shift could reshape how nations approach conflict and diplomacy. Smaller states may feel emboldened to resist great-power pressure, while larger militaries may face new constraints on intervention. Defense budgets and procurement priorities could change as expensive offensive systems lose value. The broader public may see fewer decisive military victories and more prolonged stalemates, potentially altering perceptions of military strength as a tool of national policy.
