Bernard Woolley: What if he demands options?
Sir Humphrey Appleby: Well, it's obvious, Bernard. The Foreign Office will
happily present him with three options, two of which
are, on close inspection, exactly the same.
Sir Richard Wharton: Plus a third which is totally unacceptable.
Sir Humphrey Appleby: Like bombing Warsaw or invading France.
But you have to be very careful not to overestimate the person, and end up having him command you to invade France. Giving an artificial bad option can be a great move, but it's dangerous.
