Background
The strategy of wearing down an adversary through sustained losses rather than decisive battle, attrition favours the side willing to absorb more punishment. In conventional warfare it typically advantages the larger force; in asymmetric conflict the calculus inverts, because the weaker side may accept casualties the stronger side's domestic politics cannot sustain.
Attrition has become the defining dynamic of the 2026 Iran conflict, with CENTCOM logging 9,000 targets destroyed in 25 days and 130 Iranian warships sunk , yet the IRGC fired its 70th wave of operations despite losing four commanders in a single week .
The Iran conflict illustrates both dynamics simultaneously. The US is attriting Iranian military capacity at industrial scale, yet Iran is attriting American political will and Gulf economic stability. Overnight strikes killed 300 Basij field commanders , but the IRGC's institutional depth means replacements arrive faster than the US can eliminate them. Both sides are losing; neither is winning.
