Why so many of us were wrong about missile defense

Cost Asymmetry and Economics of Defense

• Many focus on the unfavorable cost ratio: cheap drones/missiles forcing defenders to expend very expensive interceptors, which seems unsustainable in prolonged conflicts.
• Others argue you must compare to the value protected: spending millions per interceptor is rational to save billion‑dollar assets or major cities.
• There is debate over whether this “cost‑exchange” framing ignores human lives and infrastructure, versus seeing it as necessary armament economics.
• Some worry Western stockpiles (e.g., Patriot interceptors, artillery shells) are limited even if budgets are large.

Emerging Technologies and Counters

• Slow drones are seen as relatively easy targets (guns, cheaper interceptors, dedicated anti‑drone systems).
• Laser and directed‑energy systems are repeatedly cited as a key future solution, potentially reducing per‑shot cost to a few tens of dollars of electricity.
• Kinetic intercept is described as technically mature; main hard problems are materials at hypersonic speeds and high‑throughput sensing/processing.

How to Interpret Iran’s Strike on Israel

• One camp: Iran staged a calibrated “fireworks show” or warning shot—telegraphing attacks, separating drone/missile waves, possibly even leaking targets—aimed at domestic prestige and deterrence without major escalation.
• Another camp: Iran tried to overwhelm defenses and largely failed; many missiles reportedly malfunctioned, and interception success was very high.
• Counterpoint: even with help from multiple allies, some ballistic missiles still got through, suggesting defenses can be saturated by larger or better salvos.
• Disagreement remains over actual dud rates, costs on each side, and what the performance implies for future large‑scale attacks.

Nuclear and Strategic Context

• Several distinguish between theater missile defense (Patriot, S‑400, David’s Sling) and the impossibility of reliably stopping an all‑out nuclear exchange; arms control is still seen as essential there.
• Some fear improved defenses might embolden “nuclear chicken,” pushing crises closer to the threshold.

US Military Spending, Politics, and Accountability

• Some see the recent performance as vindicating long‑criticized programs (missile defense, F‑35), implying high R&D outlays paid off.
• Others argue this does not justify vast, opaque budgets or the idea that defense policy should be insulated from democratic scrutiny.
• There is tension between prioritizing military readiness versus redirecting funds to climate, health, or AI, given long‑term existential risks.
