This is the real problem with drones. America is the richest country in the world. Therefore, it's in our interest to make war as expensive as possible, since we are well positioned to win a costly war. On the other hand, drones are cheap and getting cheaper. It's suicidal for us to invest our resources in lowering the cost of entry to war, and yet we do so blithely. When we are attacked by cheap $100,000 or $10,000 drones, who will we blame for not keeping the cost of a cruise missile up in the millions besides ourselves?
