The author argues that modern warfare has fundamentally changed - it's now much harder and more expensive to finish off enemies completely than to damage them initially. Even though the US military can destroy most of an enemy's capabilities relatively easily, getting that last bit of victory costs way more and doesn't guarantee the political goals will be achieved.
Conclusion
Modern warfare has reached a structural condition where achieving the final 10% of military degradation against determined adversaries costs more than the first 90%, making conventional military superiority insufficient for achieving political objectives
Premises
- The cost curve of warfare has inverted, with the last 10% of military degradation now more expensive than the first 90%
- Recent conflicts (Ukraine-Russia, Iran operations) demonstrate that massive military superiority doesn't translate to proportional territorial gains or political outcomes
- Cheap precision weapons and unmanned systems have democratized organized violence, allowing weaker forces to impose disproportionate costs
- The arithmetic of modern air warfare favors attackers: Iranian Shahed drones cost $20-50k while Patriot interceptors cost $4+ million
- Ukraine's $250-300k maritime drones forced withdrawal of the entire Russian Black Sea Fleet, achieving sea denial at a fraction of traditional naval costs
- Even after massive degradation of Iranian military infrastructure, further escalation would require accepting heavier costs for diminishing returns
Assumptions
- Military effectiveness should be measured by cost-efficiency and political outcomes, not just battle damage assessments
- Technological advances in cheap precision weapons represent a permanent shift rather than temporary advantage
- Adversaries will continue to adapt asymmetric strategies rather than compete conventionally
- The current cost ratios between offensive and defensive systems will persist or worsen
- Political objectives require more than military degradation to achieve
