Modern warfare is shaping up to be more complex than imagined

Initial superiority determines outcomes less than the ability to learn, adjust and endure in a highly dynamic theatre of war

The juxtaposition of the Russia-Ukraine war and unfolding US-Israel-Iran war offers a compelling window to the evolving character of contemporary warfare.

One is a protracted, grinding contest of endurance; the other, a sharp demonstration of rapid, multi-domain coercion. Yet, taken together, they underline a common truth: technological change has not simplified war, it has made it more complex, more diffuse and less predictable. If anything, the promise of decisive victory has receded, replaced by a spectrum of outcomes shaped by persistence, adaptability and the management of escalation.

Ukraine has come to embody the logic of attrition in the 21st century. The battlefield is saturated with low-cost, high-impact systems, where the denial of air superiority, rather than its attainment, has defined the operational tempo. Russia’s initial assumptions of a swift victory underestimated both Ukrainian resilience and Western cohesion. What followed has been a slow recalibration, with Moscow shifting to a long-war footing, leveraging external partnerships and informational strategies, even as it absorbs sustained economic and military pressure. The steady flow of Western military assistance has not decisively tilted the balance, but it has ensured that Ukraine remains in the fight, transforming the conflict into a test of endurance rather than manoeuvre.
