Well, Alexis, if I may call you that, you made the chief points. The defence industry sizes itself according to the level of demand, and in the U.K., too, we're boosting munitions production capacity.
I think there's an important point, which is that, the simpler the product—and an artillery shell is, let's face it, a fairly simple product—the more it can be automated and the easier it is to increase production capacity in an acceptable way. The more that increasing production capacity involves employing a lot of people, then, as soon as that war demand disappears, you have to decide what you're going to do with those people. You can leave a machine working eight hours a day for five days and switch it to 24 hours, but you can't take a person who's working eight hours a day and turn that to 24 hours; you have to employ more people. Alexis got it; it's really difficult.
