Au contraire. There is nothing sacrosanct about the US Constitution - it is a set of guiding principles like any other, with some excellent aims, and some decidedly iffy ones. But as long as the US is signatory to the UN Charter and the International Courts of Justice, (amongst other international treaty organisations) it is subservient to, and bound by, international law. If it flouts international law, as it, and several of its lackeys, did in the instance of Iraq, it commits a crime against humanity. None of us, irrespective of how rich we are, or how many carrier fleets we field, is above the law.
