certainly not justified during … [1967 and] 1968." The BND's military work "had been outstanding", and in certain sectors of the intelligence field the BND still showed brilliance: in Latin America and in the Middle East it was regarded as the best-informed secret service. The BND offered a fair and reliable amount of intelligence on Soviet and Soviet-bloc forces in Eastern Europe, regarding the elaboration of a NATO warning system against any Soviet operations against NATO territory, in close cooperation with the Bundeswehr (German Armed Forces). One high point of BND intelligence work culminated in its early June 1967 forecast – almost to the hour – of the outbreak of the Six-Day War in the Middle East on 5 June 1967. According to declassified transcripts of a United States National Security Council meeting on 2 June 1967, CIA Director Richard Helms interrupted Secretary of State Dean Rusk with "reliable information" – contrary to Rusk's presentation – that the Israelis would attack on a certain day and time. Rusk shot back: "That is quite out of the question. Our ambassador in Tel Aviv assured me only yesterday that everything was normal." Helms replied: "I am sorry, but I adhere to my opinion. The Israelis will strike and their object will be to end the war in their favor with extreme rapidity." President Lyndon Johnson then asked Helms for the source of his information. Helms said: "Mr. President, I have it from an allied secret service. The report is absolutely reliable." Helms' information came from the BND. A further laudable success involved the BND's activity during the Czech crisis in 1968; by then, the agency was led by the second president, Gerhard Wessel. With Pullach cryptography fully functioning, the BND predicted an invasion of Soviet and other Warsaw Pact troops into Czechoslovakia. CIA analysts on the other hand did not support the notion of "fraternal assistance" by the satellite states of Moscow; and US ambassador to the Soviet Union, Llewellyn Thompson, quite irritated, called the secret BND report he was given "a German fabrication". At 23:11 on 20 August 1968, BND radar operators first observed abnormal activity over Czech airspace. An agent on the ground in Prague called a BND out-station in Bavaria: "The Russians are coming." Warsaw Pact forces had moved as forecast. However, the slowly sinking efficiency of BND in the last years of Reinhard Gehlen became evident. By 1961,
