Until now the western formula has been that the welfare of the Syrian people was best served by working to destroy Isis and to remove the Assad regime, while caring for huge numbers of refugees in camps in neighbouring countries. If peace had been more attainable in Syria, this approach might have been acceptable. But it neglected the need for the protection of civilians in their own country. The failure to protect civilians in Bosnia and in Rwanda led to the emergence in 2005 of the doctrine of the responsibility to protect, which the United Nations formally adopted in 2009. It was supposed to be a lesson learned forever, but it seems to have been quickly forgotten in Syria.
