Professor Akhavan, I want to ask this very quickly, because I have literally a minute left.
You know UN resolution 2178, I'm sure, which states in part:
...Member States must ensure that any measures taken to counter terrorism comply with all their obligations under international law...underscoring that respect for human rights, fundamental freedoms and the rule of law are complementary and mutually reinforcing with effective counter-terrorism measures, and are an essential part of a successful counter-terrorism effort....
It goes on to talk about all member states having to abide by international law and comply with that.
As an expert in the field of international law, can you comment on the importance of ensuring that Canada's response to ISIS corresponds with our international legal obligations and what else we can do to ensure that we gather evidence to bring perpetrators to justice?
