colonialism", and that the "backward" Papuans were not ready for independence; while the Indonesian position argued that Indonesia was already ethnically diverse, that Indonesia wanted to reunite territories separated by colonialism, and that Dutch arguments about democracy were "a trick" to create "at the doorstep of Indonesia a puppet state... under Dutch tutelage". By March 1961, Indonesia had indicated agreement for United Nations trusteeship on condition that it would not be called a trusteeship. Both supporters of Indonesia and supporters of the Netherlands in the administration cast their positions as favourable to anticolonialism. Although the idea of Papuan independence appealed to senior advisers in the U.S. government, few thought it realistic. US officials were also concerned about world opinion in favour of Indonesia; diplomatic displays of Third World solidarity were increasing, and in January 1962, Egypt closed its Suez Canal to Dutch ships as a protest against the Netherlands' New Guinea policy. In mid-January, Robert F. Kennedy, President Kennedy's brother, travelled to Jakarta and announced that the United States, "as a former colony, is committed to anti-colonialism". President Kennedy later met with both the Dutch Foreign Minister Joseph Luns and Sukarno, with both agreeing to a United Nations Trusteeship but disagreeing on the details. When the United States sponsored a "compromise" resolution in the United Nations which Indonesia opposed, relations with Indonesia soured. In December, National Security Advisor McGeorge Bundy decisively advised Kennedy towards a more pro-Indonesian position, lest the "Soviet bloc... draw Indonesia even closer to it". American-mediated secret Ambassadorial level talks began in March 1962, without preconditions, but Sukarno was sceptical of American intentions. The talks were held at the Huntland estate at Middleburg, Virginia. An outline of the plan by American diplomat Ellsworth Bunker in 1962 proposed that the Netherlands transfer control over New Guinea to neutral United Nations administrators, who would be gradually replaced by Indonesian administrators, and then entirely to Indonesia, which would then be required to organize a referendum "to give the Papuans freedom" with the United Nations Secretary-General and other United Nations personnel. The Netherlands responded that the proposal was a "shocking betrayal by the United States", initially wanting the referendum to take place under UN administration. Although after the United States threatened to make the negotiations public, it acceded with the addition of a "right to self-determination" into the agreement.
