Supernational Sovereignty is a fancy way of saying the US government thinks it has the right to tell the whole world what to do. From Philip Giraldi at unz.com:
One of the most disturbing aspects of American foreign policy since 9/11 has been the assumption that decisions made by the United States are binding on the rest of the world, best exemplified by President George W. Bush’s warning that “there was a new sheriff in town.” Apart from time of war, no other nation has ever sought to prevent other nations from trading with each other, nor has any government sought to punish foreigners using sanctions with the cynical arrogance demonstrated by Secretary of State Mike Pompeo. The United States uniquely seeks to penalize other sovereign countries for alleged crimes that did not occur in the U.S. and that did not involve American citizens, while also insisting that all nations must comply with whatever penalties are meted out by Washington. At the same time, it demonstrates its own hypocrisy by claiming sovereign immunity whenever foreigners or even American citizens seek to use the courts to hold it accountable for its many crimes.
The conceit by the United States that it is the acknowledged judge, jury and executioner in policing the international community began in the post-World War 2 environment, when hubristic American presidents began referring to themselves as “leaders of the free world.” This pretense received legislative and judicial backing with passage of the Anti-Terrorism Act of 1987 (ATA) as amended in 1992 plus subsequent related legislation, to include the Justice Against Sponsors of Terrorism Act of 2016 (JASTA). The body of legislation can be used to obtain civil judgments against alleged terrorists for attacks carried out anywhere in the world and can be employed to punish governments, international organizations and even corporations that are perceived to be supportive of terrorists, even indirectly or unknowingly. Plaintiffs are able to sue for injuries to their “person, property, or business” and have ten years to bring a claim.
