At Asia Times, Alfred W McCoy identifies what he dubs “the real American exceptionalism.” A snippet:
Washington, more than any other power, created the modern international community of laws and treaties, yet it now reserves the right to defy those same laws with impunity. A sovereign ruler should, said Schmitt, discard laws in times of national emergency. So the United States, as the planet’s last superpower or, in Schmitt’s terms, its global sovereign, has in these years repeatedly ignored international law, following instead its own unwritten rules of the road for the exercise of world power.
