My second question is about the tendency to substitute the strategy for everything. The shipbuilding strategy was to replace certain capabilities. Submarines, which you talked about, or long-range patrol aircraft are not part of the shipbuilding strategy, but we talk about the shipbuilding strategy as if it were the solution.
As somebody who represents a base where submarines have been refitted, I was glad to hear you talking about submarines. Could you talk more about the necessity, especially in the Asia-Pacific region, of maintaining our submarine capacity?
