If I understand correctly your argument is that we should ignore international law. So correctly if I'm wrong, but you were definitly saying "We should not follow the law." You also said, to support you argument, "For powerful nations it [the law] can just be ignored." Which, I think, is the same as "because other people don't follow the law."
So explain to me, how were you not saying "We should not follow the law, because other people don't follow the law."?
