"We are told that the intention is to substitute law for war; that that is, in essence, the whole object of the United Nations. It is another of those comfortable slogans expressing a desire felt by all of us in rhyming monosyllables, which seem to have an almost hypnotic effect. Of course, we all want the rule of law amongst nations; but what are the laws which we wish to rule? Evidently, it is not the laws accepted in principle for thousands of years—the fulfilment of contracts and the sanctity of treaties. Rather it seems to be commandments promulgated ad hoc by the Assembly whenever differences arise. That is submission to an arbitrary body. It is not law."
