The Group of Two (G-2 or G2) is a proposed informal special relationship between the United States of America and the People's Republic of China.
 Originally initiated in 2005 by C. Fred Bergsten as primarily an economic relationship, it began to gain wider currency and scope from foreign policy experts as a term recognizing the centrality of the Sino-American relations near the beginning of the Obama Administration.
 Prominent advocates include former National Security Advisor Zbigniew Brzezinski, historian Niall Ferguson, former World Bank President Robert Zoellick and former chief economist Justin Yifu Lin.
Sir Halford John Mackinder PC (15 February 1861 – 6 March 1947) was an English geographer, academic, politician, the first Principal of University Extension College, Reading (which became the University of Reading) and Director of the London School of Economics, who is regarded as one of the founding fathers of both geopolitics and geostrategy.

Zbigniew Kazimierz "Zbig" Brzezinski ( ; ] ; March 28, 1928 – May 26, 2017) was a Polish-American diplomat and political scientist.
 He served as a counselor to President Lyndon B. Johnson from 1966 to 1968 and was President Jimmy Carter's National Security Advisor from 1977 to 1981.
 Brzezinski belonged to the realist school of international relations, standing in the geopolitical tradition of Halford Mackinder and Nicholas J. Spykman.
Patrick O'Sullivan is an Irish-British scholar and author of major works in the field of Military geography.
 He is the author of the oft-cited texts "The Geography of Warfare" and "The Geography of War in the Post-Cold War World".
 Though the former was published in 1983 and the latter in 2001, these works remain the seminal texts of Military geography from a civilian publisher, due in large part to the present lack of interest in the subfield among geographers, aside from a small handful who critique militarization through critical theory.
 In his 1986 book "Geopolitics", Patrick O'Sullivan makes a geographically-based case against the proliferation of nuclear weapons during the Cold War, arguing that nuclear weapons pose a threat largely because they reduce the significance of both physical distance and national borders, which would otherwise function as a deterrent to the likelihood of direct military engagement.
 Patrick O'Sullivan is also known to a lesser extent for his work on the social scientific study of railway transportation in Britain as well as an autoethnographic Cultural Geography essay discussing the relevance of expatriate identity.
 Starting in 1994, he taught at Florida State University, and now holds the status of professor emeritus.
 His academic writing incorporates elements of a regional geography focus with aspects of behavioral geography, and often takes a similarly explanatory and analytical approach to the Realist school of International Relations' focus on the behavior and motivations of states, though from a more geopolitical angle and with a greater focus on the decisions of individual leaders.
 Unlike many other authors and scholars of human geography, his work is not as overtly hostile to environmental determinism or environmental possibilism.
The Anatomy of Revolution is a book by Crane Brinton outlining the "uniformities" of four major political revolutions: the English Revolution of the 1640s, the American, the French, and the 1917 Russian Revolution.
 Brinton notes how the revolutions followed a life-cycle from the Old Order to a moderate regime to a radical regime, to Thermidorian reaction.
 The book has been called "classic, "famous" and a "watershed in the study of revolution," and has been influential enough to have inspired advice given to US President Jimmy Carter by his National Security Advisor Zbigniew Brzezinski during the Iranian Revolution.
The Grand Chessboard: American Primacy and Its Geostrategic Imperatives (1997) is one of the major works of Zbigniew Brzezinski.
 Brzezinski graduated with a PhD from Harvard University in 1953 and became Professor of American Foreign Policy at Johns Hopkins University before becoming the United States National Security Advisor during 1977–81 under the administration of President Jimmy Carter.
Nicholas John Spykman (13 October 1893 – 26 June 1943) was an American political scientist who was one of the founders of the classical realist school in American foreign policy, transmitting Eastern European political thought into the United States.
 A Sterling Professor of International Relations, teaching as part of the Institute for International Studies at Yale University, one of his prime concerns was making his students geographically literate—geopolitics was impossible without geographic understanding.
 His work on geopolitics and geostrategy led him to be to known as the "godfather of containment."
