In this post, I explore the punitive justifications for the recent strikes against Syria in response to the alleged use of chemical weapons. In the previous post, Sara was right to call into question the HI justification for the strikes provided by Theresa May. Indeed, even if one could assume that the strikes could satisfy the just cause criterion (and this is a big if), it’s doubtful that other ad bellum criteria could be met (proportionality and reasonable chance of success). The situation is Syria is complicated with multiple parties involved, either directly or through proxy. It is, therefore, difficult to determine what success would mean in this context and, correspondingly, what would be counted as proportionate force. I think Sara is right that the strikes could not be justified on the basis of HI. But, I ask, are there any other justifications for these strikes?
