The US ambassador to Belgium and minister to Switzerland and conference delegate, Hugh S. Gibson, had observed not long after the London Conference, the United States had decreased interest in the new conference because treaties already limited its navy, its army was so small that reduction was ludicrous, and the proposed measures of air limitation were so vague that they meant little. Gibson wrote that the conference would "probably meet in February or March 1932 and, discouraging as it may sound, it will probably go on and on." He had come to believe that armaments would never be abolished completely but that treaties could perhaps maintain military balances.
