The United States is the World Policeman

The role of the Unites States as the world policeman is a more just world.

One of the most popular public global debate topics is: The U.S. is the World Policeman. American policymakers have been largely loathe to accept the title with an enduring conviction since Vietnam that the role is not sustainable. President Warren Harding’s memorial to the “unknown soldier” is a testament to the enduring isolationism of the American public and the keen aversion to risking the precious lives of young Americans abroad. John Quincy Adams’ proclamation to the Congress while serving as Secretary of State in 1821 remains a compelling admonition to present policy makers: “America goes not abroad in search of monsters to destroy.”

Despite these profound historical caveats, America does appear to be the indispensable power in global affairs and the current military engagement in Iran deepens that reality and urges growing acceptance that the United States is ‘the world’s policeman.’ The abrupt capture of Venezuelan strongman Nicolás Maduro eviscerated the global mood of bluffing or relying upon Trump’s promise to not increase U.S. commitments for military intervention. The ease of Trump’s military entries and exits from diverse locations defies one of the most important rhetorical premises rooting American isolationism: “quagmire.” The term remains the media’s ‘gotcha’ to presidential plans of “limited intervention.” The 21st century version of the quagmire problem is the Iraq war of 2003 fought by President Bush. Trump himself denounced the war as one of the nation’s greatest mistakes. Punditry successfully lodged the enduring false memory that Saddam Hussein ‘never had weapons of mass destruction,’ -- though the dead bodies of Kurdish children at Halabja bear the marks of a dictator who used chemical weapons as “human insecticide.”

From Vietnam to current conflicts, American public culture........
