We believe that legal obligation lies in a number of respects.
The first is under the counterterrorism resolutions of the Security Council, those two resolutions that address foreign fighter obligations of states, where it is really clear that the only international law-compliant response to the challenges posed by foreign fighters and their families or associated individuals is return. It's the only way that one will get prosecution, which is an obligation for serious crimes under international law if evidence exists to prosecute.
It's the only way in which victims of terrorism will actually see a process that will meet their needs. From the long-term strategic and security perspective, which the mandate regularly engages with security services around the world, there's also a clear sense that this is in the long-term security interest for states like Canada. Leaving these nationals in a place where they will fester, which will create the ideal breeding grounds for further violence, is not in anyone's long-term interest.
Under human rights, I would just say that under the treaty obligations in relation to torture and extrajudicial and arbitrary execution, there's a really clear and compelling positive obligation on Canada to prevent serious harm to its nationals, which it is in a position to prevent.
