1. If it is a breach of international law, who cares? When you are the big bully, you can do what you want. If you happen to NOT be quite big enough to do your dastardly deeds right out in the open, and you are smart enough to realize this so that you do your dastardly deeds covertly, if you can get away with it, your strength is in your shrewdness.

2. The United States is different from all other countries. Right in the formal backbone of law upon which the law of the whole country relies - the Constitution - there is Article 1, Section 10, Paragraph 1, which contains the "contract clause." Properly applied, this clause nullifies everything in every treaty the United States signs. If the U.N. and other countries that sign treaties with the United States don't realize this, too bad.

Any rhetoric about the United States breaking international law is simply a bunch of words that have no effect... except, possibly, to get any country or person that agrees with the rhetoric, sanctioned by the United States. Is this just? Probably not. But it is what it is.
