For three of the novels, "Goldfinger", "Live and Let Die" and "Dr. No", it is Bond the British agent who has to sort out what turns out to be an American problem, and Black points out that although it is American assets that are under threat in "Dr. No", a British agent and a British warship, HMS "Narvik", are sent with British soldiers to the island at the end of the novel to settle the matter. Fleming became increasingly jaundiced about America, and his comments in the penultimate novel "You Only Live Twice" reflect this; Bond's responses to Tanaka's comments reflect the declining relationship between Britain and America—in sharp contrast to the warm, co-operative relationship between Bond and Leiter in the earlier books.
