He served as an envoy to Berlin from 1969 , then as the Norwegian ambassador to Israel from 1971 to 1975 , to the Soviet Union from 1975 to 1979 , to Canada from 1979 to 1983 and to the Netherlands from 1983 to 1988 . As a diplomat he was regarded by US authorities in 1975 as " perceptive , capable and highly intelligent , with a fine appreciation of the ' realities ' of dealing with the Soviets . Although understanding and helpful to Americans , he is reportedly an independent thinker and a skillful , tenacious advocate of the Norwegian position . " While serving in Tel Aviv he also acted as the Norwegian ambassador to Cyprus . His tenure coincided with a very turbulent period in Israeli society , with the Yom Kippur War , the Munich massacre , and the Mossad assassination of Ahmed Bouchiki in the small Norwegian town Lillehammer in 1973 . Bouchiki was thought to have a connection with the Munich massacre , and as such assassinated as a retaliation , but this proved to be groundless . In a 1974 letter to his employers in the Ministry of Foreign Affairs of Norway , Graver explained the Bouchiki case as a result of Western European countries failing to heed a call from Israel to cooperate on counter-terrorism . As Norwegian authorities detained the Mossad agents who killed the innocent Bouchiki , an Israeli group planned to kidnap Graver and demand the liberation of the agents as a ransom . This surfaced in a 1987 book by Yair Kotler on Meir Kahane , the alleged leader of the plot
