Thats what they said about airplanes a few short years ago..
I am guessing by your oversimplified comment that your point is you can make all things stealthy. Your correct to some degree, but we dont want to take a $25,000 Guided bomb and spend 50,000 to make this expendable stealthy. The ordnance needs to be cheap so we can buy lots of them. So your point is made, but not a very smart choice given limited budgets with LOTS of other big ticket items.
