Syria was one of seven remaining nations on the planet that haven’t ratified the treaty, and the list will now only include six: Israel, Myanmar, Angola, Egypt, North Korea, and South Sudan.

The United Nations has confirmed receipt of the documents verifying Syria’s ratification of the CWC, and Assad has indicated that he intends to have a full list of his nation’s arsenal available for the UN within 30 days.

The 30 days is a specific requirement of the CWC, though Secretary of State John Kerry has angrily rejected it as unacceptable, and has suggested the US might attack Syria if they stick to the actual terms of the deal.
