No, you sent lots of things from warehouses that ① originally cost billions to buy and ② have limited shelf life.

You've seen the Patriot missiles that the Ukrainians have used to such good effect. Those were made thirty years ago. They were expensive to make, then. Sending them is a great thing to do, no question about it. But if you want to talk about billions of crrent expenses, then I it's wrong to talk about money spent in the nineties. You should instead think about their replacement cost. You need to replace them now. But how long was their shelf life — would you need to replace them soon anyway?
