Certainly I would put a question mark over the cost element. I think you would be very well advised--please, forgive me for suggesting this--to take a forensic look at exactly what these costs are and drive out of the people involved much more precisely how much it is going to cost you to acquire and run these particular assets.
Now, we can give you these figures. We will give you very precise figures and you can look at them very closely. You can benchmark everyone against us if you wish. But I do feel that when one particular supplier says they are the best, the cheapest, and the only selection to be made, there's probably a question mark that you should have over that, and it's probably in your best interests. Forgive me for saying so, but you need to take a forensic look, as I say, even if it's a fast-pass look at what's available and what may be your better interests. There's nothing to lose. It may well be that the F-35 is the right aircraft for your country. But what we would say is perhaps you might be best served to check first on a number of criteria.
