On 16 October 1945, before the UN Charter had even entered into force, retired U.S. Supreme Court Justice Owen J. Roberts and former New Hampshire Governor Robert P. Bass held a conference in Dublin, New Hampshire, which passed the Dublin Declaration. It stated that the UN Charter was inadequate to preserve peace and proposed the transformation of the UN General Assembly into a world legislature, opining, "Such a government should be based upon a constitution under which all peoples and nations will participate upon a basis of balanced representation which will take account of natural and industrial resources and other factors as well as population. It cannot be based on treaties...in which the states...act and vote as states". It called for "limited but definite and adequate power for the prevention of war." Grenville Clark and other participants in the Dublin conference went on to become active in the United World Federalists (UWF) and the global World Federalist Movement. UWF enjoyed some success in the postwar period, as 23 state legislatures passed bills supporting the organization's goals, but McCarthyism prompted many prominent members to resign lest Senator Joseph McCarthy ruin their careers. In the United States, internationalism came to be associated with communism.
