I skimmed it as well. Looks fairly comprehensive, and not that sinister . . . unless the word "international" makes one break out in hives.
"In refusing to accept either the interpretation of international law adopted by other states or the authority of international institutions claiming the right to adjudicate international law claims, the United States is not violating its international obligations or seeking impunity. It is merely exercising its indisputable rights as an independent sovereign."
In this context you should be concerned.
Luckily, at least for the most part, the Judiciary isn't biting.
