"It is not always those who secure public praise to whom thanks are mainly due, and the work unknown to the public which is done behind the scenes is often a large factor in the success which has been obtained". The ideal was not always upheld, and national preferences were never really abandoned. New under-secretaries-general who were appointed were more often than not of the same nationality, with candidates of smaller powers excluded. Drummond did not practice what he preached, which created small national islands from which the appointed officials conducted national, rather than international, politics. In 1929, the Assembly decided to make a thorough investigation of the secretariats, the International Labour Organization and the Permanent Court of International Justice. The minority report showed that the political influence in substantive issues by the secretariats and its main officers was enormous and could not be overlooked. However, that was not recognised by Drummond before the 1950s and until then had readily defended the notion of nonpolitical character of international secretariats. Despite the political character of the international civil service, the Secretariat came to be widely recognised as an instrument of the highest efficiency and the structural framework became a model for future international civil services, such as seen in the United Nations. Role during crises During Drummond's secretary-generalship were several crises that called for his attention. The League of Nations' Council relied on the willingness of its members to use their militaries to apply its collective security mandate during crises. Many of them centred on border disputes from the collapse of empires after the First World War. As the League got involved in such matters throughout the 1920s with members and non-members alike, Drummond was at the centre of the talks and the negotiations. The League was involved in disputes in Latin America, the Baltics and then China. Peter Yearwood argues that although Drummond was an idealist, as were most other people, he also 'made use' of his connections in politics. Drummond was widely regarded as somebody who shied away from the public and political limelight, despite the high-profile nature of his position. He managed to achieve that but was believed to be highly political behind the scenes. He was often forced to appease various nations because he often lacked support from governments. One example was his dealings with Benito Mussolini's policies in the 1920s towards the Balkans, Africa and the
