Any act like this makes the UN security council a irrelevant organisation.
The security council was established to ensure that there was never again a World War!
And any action which by passes the security council by its members can only be seen as an rogue nation action!
Which should require the rogue nations immediate expulsion from the UN.
The U.N.’s General Assembly met informally 20th October 2016 Thursday to discuss whether to take steps to override the Security Council on the Syrian conflict
This action is being floated because they can not deceive Russia and China to overthrow Assad in Syria!
