Even worse, Suppose I can easily obtain and assemble the parts I need for an attack. But your, for instance, Patriot missiles take rather longer to assemble (as they are much more complex). If you have 50 missiles at hand, I only need to launch 51 attacks before you get your next shipment of missiles.
Clearly you are correct inasmuch as you won't spend 1,000,000,000 dollars to defend 200,000,000 dollars of assets. But the relative costs of defense and offense do matter.
