Citizens for Global Solutions is a grassroots-level membership organization[1] in the United States working towards the establishment of a world government[2] in order to avoid future atomic wars.

[9] Cord Meyer IV was the first president of the organization, with Grenville Clark, Thomas K. Finletter, Wallace Trevor Holliday serving as vice-presidents.

[1][3] In 1948, Cord Meyer was invited to attend a meeting of the Emergency Committee of Atomic Scientists (ECAS) where he met Albert Einstein,[10][11] Leo Szilard and many of the other leading nuclear physicists.

[13][14] In June, 1951, in his letter to Harrison Brown, Einstein described the United World Federalists as: "the group nearest to our aspirations".

[8] In 1975, the organization turned its focus to educational activities as the World Federalist Association (WFA), while members who wanted to continue political action efforts formed the Campaign for UN Reform (CUNR).
