Pax Americana[1][2][3] (Latin for 'American Peace', modeled after Pax Romana and Pax Britannica), also called the "Long Peace", is a term applied to the concept of relative peace in the Western Hemisphere and later in the world after the end of World War II in 1945, when the United States[4] became the world's dominant economic, cultural, and military power.
In this sense, Pax Americana has come to describe the military and economic position of the United States relative to other nations. The U.S. Marshall Plan, which saw the country transfer $13.3 billion (the equivalent of $173 billion in 2023) in economic recovery programs to Western European countries, has been described as "the launching of the Pax Americana".[5]

[...] Felix Adler [states ...] "if, instead of establishing the Pax Americana so far as our influence avails throughout this continent, we should enter into' the field of Old World strife, and seek the sort of glory that is written in human blood." Here it is assumed that we have failed in establishing self-government, and propose to substitute, at least in other lands, an Old World form of government. This sort of argument has no effect on the expansionist, because he believes that we have magnificently succeeded in our problem, in spite of failures, neglects, and violations of our own principles, and because what he wishes to do is, not to abandon the experiment, but, inspired by the successes of the past, extend the Pax Americana over lands not included in this continent.")
