Recent military conflicts, particularly the ongoing Russia-Ukraine war and India's Operation Sindoor, reveal a significant shift in warfare dynamics, emphasizing endurance and cost-effectiveness. The concept of an 'economy of attrition' is becoming critical, as demonstrated by Iran's extensive use of low-cost munitions, which has overwhelmed expensive interceptors from the US and Israel. Despite claims of high interception rates, the cost asymmetry favors Iran, prompting military strategists to reconsider future conflict scenarios. Ukraine has also adapted by developing its own low-cost interceptors, achieving a remarkable economic agility that has allowed it to reduce reliance on Western support. As India faces potential threats from Pakistan and China, it must enhance its layered air defense systems, incorporating cost-effective solutions to counter saturation attacks. The need for resilience in military production and strategy is underscored by the experiences of nations like Iran and Ukraine, which have managed to sustain prolonged conflicts through decentralized and low-tech approaches. Ultimately, the ability to endure and adapt will define success in modern warfare.
