 Casino Royale deals with the question of Anglo @-@ American relations , reflecting the real @-@ world central role of the US in the defence of the West . The academic Jeremy Black points to the 1951 defections of two members of MI6 — Guy Burgess and Donald Maclean — to the Soviet Union as having a major impact on how Britain was poorly viewed in US intelligence circles ; Fleming was aware of this tension between the two countries , but he did not focus on it too strongly , and Bond and Leiter 's warm relationship did not reflect the reality of the US @-@ UK relationship .
