Its long-term strategy, however, is illustrated by the analogy of the three Siamese fighting fish Blofeld keeps in an aquarium aboard SPECTRE's yacht in the film version of "From Russia with Love". Blofeld notes that one fish is refraining from fighting two others until their fight is concluded. Then, that cunning fish attacks the weakened victor and kills it easily. Thus SPECTRE's main strategy is to instigate conflict between two powerful enemies, namely the superpowers, hoping that they will exhaust themselves and be vulnerable when it seizes power. SPECTRE thus works with, and against, both sides of the Cold War. For example, in the film "Thunderball", it simultaneously blackmails a Japanese double agent, distributes Red Chinese narcotics in the United States, kills a defector to the USSR on behalf of the French Foreign Ministry, and threatens NATO with stolen nuclear weapons, while continuing ordinary criminal operations such as advising on the British Great Train Robbery.
