"Those who use chemical weapons against defenseless men, women and children should and must be held accountable," Biden told his Houston audience, without mentioning American use of DU WMDs.
At the United Nations, calmer, more rational heads prevail
At the United Nations, Secretary General Ban Ki-moon maintained a more diplomatic composure. In a statement about the UN investigation headed by Under-Secretary-General Angela Kane, he said:
"The Secretary-General now calls for the mission, presently in Damascus, to be granted permission and access to swiftly investigate the incident which occurred on the morning of 21 August. A formal request is being sent by the United Nations to the Government of Syria in this regard. He expects to receive a positive response without delay."
In a second statement, regarding the use of chemical weapons as a violation of international humanitarian law, the secretary-general concluded:
"The Secretary-General reiterates that any use of chemical weapons by any side under any circumstances would violate international humanitarian law."
