The conflict over the sovereignty over Irian Barat (West New Guinea) was poisoning relations between Jakarta and the Hague. This last territory of the former Dutch East Indies was excluded from being transferred to Indonesia during the Round Table Conference in Holland which led on December 30, 1949 to the final legal transfer of the former Dutch Asian empire to Indonesia. West New Guinea remained, however, part of the kingdom of the Netherlands. President Sukarno and the entire Indonesian nation were furious and so was Willem Oltmans!
When we, Indonesian Air Force officers training in the United Kingdom, heard about Wim's attitude as a Dutch citizen towards the policy of his own government at a weekend in London, where we assembled to hear the report of our delegation, we concluded that this Dutch journalist was either a lunatic or an intelligent and brilliant man with a remarkable high degree of courage, humanism and a properly developed sense of justice.
In the mid fifties, following his meeting President Sukarno in Rome and Bonn, Wim spent a year in Indonesia for the nrc newspaper and other publications. He joined president Sukarno on his trips, wherever he went in Indonesia. Later, when he was blocked from returning to Jakarta after 1957, he would meet Bung Karno in many countries including during two trips to the United-States in 1960 and 1961. Wim has written about these experiences in his book Den Vaderland Getrouwe, which I read in prison.
He learned a lot about the President and the way he used to speak directly to the people using the peoples language. One of the gifts Sukarno was provided with the ability to explain problems in simple and easily understandable terms, easily absorbed by both the so-called intellectuals as the man in the street. I am sure, that even Wim, who did not know or speak Behasa Indonesia, could easily grasp the essence of Sukarno's speeches. In 1956-1957 I did not meet Wim as yet, because I was in the United Kingdom.
In 1999, Wim was in Jakarta and was invited by Air Force Marshall A.V.M. Wisnu Djajengminardo (Also a close friend of Indro Noto Suroto and I did meet him and his wife already in 1957) in his Jakarta home to celebrate Wim's 74th birthday. Wim arrived, surprising us all, with his close friend Sukmawati Sukarnoputri, the third daughter
