In the annals of western intelligence blunders, the failure to notice the Sino-Soviet split in the frigid depths of the cold war looms very large. Despite a small group of heretical CIA officers pointing to mounting evidence from the late 1950s onwards, successive governments in Washington and elsewhere refused to believe that the two biggest members of the communist bloc actually hated each other. It was not until China and Russia fought a war along the Siberian-Manchurian border in 1969 that the sceptics finally accepted the schism was real.
在西方情報界愚蠢錯誤的編年史上,未能發現中蘇關係在冷戰正酣之際出現破裂,是非常突出的一筆。儘管美國中情局(CIA)少數非主流官員指出了從上世紀50年代末起出現的越來越多的證據,美國及其他西方國家的歷屆政府都拒不相信共產主義陣營的兩個最大成員竟然彼此憎惡。直至1969年兩國在蘇聯西伯利亞與中國東北接壤的邊界打了一仗,那些拒不相信中蘇交惡的人們才最終接受了這是真的。
