America and Americans broadly do not respect “international law” as an idea. We don’t vote for representatives in a UN House of Reps or UN Senate. And if we did why would we wish to be beholden to a majority rules vote when that majority combined might be inferior militarily.
America tolerates international law when it doesn’t interfere with our course.
The idea of a “one world government” is treated as a fringe tin hat conspiracy theory nonsense that no one is advocating for.
This happens all the time. The party out of the majority proposes moon-shot legislation knowing that it won’t pass. Because they get to go home and complain about the bad (insert party name here)s who blocked the, probably unconstitutional, bill that they proposed. Then beg for donations so they can get a seat on an important committee.
