@Kycntryboy: I don't think anyone is suggesting that UAVs will have a monopoly in the strike warfare arena - not in our lifetimes. This debate has been hashed out more times than I care to remember here, but if it makes you feel any better, I'm not worried about UAVs putting me out of a job. It's a good tool with known limitations that's not going to replace manned aircraft anytime soon (if ever).
