عالم سیاسی آمریکایی جوزف نای، یکی از مؤسسین نظریه روابط بینالملل نولیبرالیسم، استدلال کرده که منظور از گلوبالیسم هر تفسیر و توضیح جهانیست که مشخصهٔ آن شبکههایی از ارتباطات است که در فواصل بین قارهای پراکندهاند؛ در حالی که منظور از جهانیشدن افزایش یا کاهش درجهٔ گلوبالیسم است.
Globalism refers to various systems with scope beyond the merely international. It is used by political scientists, such as Joseph Nye, to describe "attempts to understand all the interconnections of the modern world — and to highlight patterns that underlie (and explain) them." While primarily associated with world-systems, it can be used to describe other global trends. The term is also used by detractors of globalization such as populist movements.
Political science definitions
Paul James defines globalism, "at least in its more specific use [...] as the dominant ideology and subjectivity associated with different historically-dominant formations of global extension. The definition thus implies that there were pre-modern or traditional forms of globalism and globalization long before the driving force of capitalism sought to colonize every corner of the globe, for example, going back to the Roman Empire in the second century AD, and perhaps to the Greeks of the fifth-century BC."
Manfred Steger distinguishes between different globalisms such as justice globalism, jihad globalism, and market globalism. Market globalism includes the ideology of neoliberalism. In some hands, the reduction of globalism to the single ideology of market globalism and neoliberalism has led to confusion. For example, in his 2005 book The Collapse of Globalism and the Reinvention of the World, Canadian philosopher John Ralston Saul treated globalism as coterminous with neoliberalism and neoliberal globalization. He argued that, far from being an inevitable force, globalization is already breaking up into contradictory pieces and that citizens are reasserting their national interests in both positive and destructive ways.
Alternatively, American political scientist Joseph Nye, co-founder of the international relations theory of neoliberalism, generalized the term to argue that globalism refers to any description and explanation of a world which is characterized by networks of connections that span multi-continental distances; while globalization refers to the increase or decline in the degree of globalism. This use of the term originated in, and continues to be used, in academic debates about the economic, social, and cultural developments that is described as globalization. The term is used in a specific and narrow way to describe a position in the debate about the historical character of globalization (i.e. whether globalization is unprecedented or not).
It has been used to describe international endeavours begun after World War II, such as the United Nations and the European Union, and also sometimes the later neo-liberal and neoconservative policies of "nation building" and military interventionism between the end of the Cold War in 1992 and the beginning of the War on Terror in 2001.
Arguments in favor
Proponents of Globalism believe in Global citizenship, that is, the problems of humanity can be resolved with Democratic Globalism. Democratic Globalism is the idea that all people matter, no matter where they live, and that universal freedom and human rights can be fostered for all mankind. World Citizens believe in Civic Globalism and that by thinking globally and acting locally they can affect positive change across all barriers.
The term "globalist" has been used a pejorative for political enemies, on the left within the context of the 1990s anti-globalization movement and protests, and on the right as a pejorative of "cosmopolitans" or those who favor internationalist projects over national ones. For example, during the election and presidency of United States president Donald Trump and members of his administration used the term globalist on multiple occasions. The administration was accused of using the term as an anti-Semitic "dog whistle", to associate their critics with a Jewish conspiracy.
History of the concept
The term first came into widespread usage in the United States. Many of these early uses of the term "globalist" in American English were pejorative uses by marginal political groups like the Ku Klux Klan and neo-Nazis, and in related anti-Semitic works like Henry Ford's The International Jew.
The modern concept of globalism arose in the post-war debates of the 1940s in the United States. In their position of unprecedented power, US planners formulated policies to shape the kind of postwar world they wanted, which, in economic terms, meant a globe-spanning capitalist order centered exclusively upon the United States. This was the period when US global power was at its peak: the country was the greatest economic power the world had ever known, with the greatest military machine in human history.  As George Kennan's Policy Planning Staff put it in February 1948: "[W]e have about 50% of the world's wealth but only 6.3% of its population. […] Our real task in the coming period is to devise a pattern of relationships which will permit us to maintain this position of disparity". America's allies and foes in Eurasia were still recovering from World War II at this time.
American historian James Peck has described this version of globalism as "visionary globalism". Per Peck, this was a far-reaching conception of "American-centric state globalism using capitalism as a key to its global reach, integrating everything that it can into such an undertaking". This included global economic integration, which had collapsed under World War I and the Great Depression.
Modern globalism has been linked to the ideas of economic and political integration of countries and economies. The first person in the United States to use the term "economic integration" in its modern sense (i.e. combining separate economies into larger economic regions) was John S. de Beers, an economist in the US Department of the Treasury, towards the end of 1941. By 1948, "economic integration" was appearing in an increasing number of American documents and speeches. Paul Hoffman, then head of the Economic Cooperation Administration, used the term in a 1949 speech to the Organisation for European Economic Co-operation. As The New York Times put it,
Globalism emerged as a dominant set of ideologies in the late twentieth century. As these ideologies settled, and as various processes of globalization intensified, they contributed to the consolidation of a connecting global imaginary. In 2010, Manfred Steger and Paul James theorized this process in terms of four levels of change: changing ideas, ideologies, imaginaries and ontologies.
