In 1949, Luns was appointed as deputy Dutch permanent representative to the United Nations. He worked closely with his new chief, Von Balluseck, a political appointee without diplomatic experience. After the Netherlands became a member of the Security Council, he temporarily chaired the Disarmament Commission. Luns was sceptical of the importance of the United Nations for international peace, believing it at times to be more like a forum for propaganda than a centre for solving international conflicts. Still, he thought that it was worthwhile to keep the UN in shape because it was the sole international organisation which offered opportunities for discussions between all states.
