There is a range of options, from easy to hard, in terms of their prospect of success for doing something.
The genocide convention was adopted in 1948. All states who are a party to that convention have a proactive obligation to prevent the various crimes in the genocide convention, which includes incitement to genocide, and to act accordingly. Only once since 1948 has a state-to-state complaint been filed in the International Court of Justice, and it was the case of Bosnia versus Yugoslavia. It took a long time to wind its way through the court, and ultimately led to an only somewhat satisfactory judgment.
But given the fact that we know that numerous genocides have in fact taken place between 1948 and the present time, the abject lack of enforcement taken by state parties to the genocide convention against other states that are committing genocide, conspiracy to commit genocide, incitement to commit genocide, etc., I think is an unfortunate legacy of our own history.
One easy thing that Canada could decide to do unilaterally, because both the Government of Iran and the Government of Canada are a party to the convention, and because under article 9 of the convention, one state can make a complaint against a second state in the court of justice, is to file a complaint on charges of incitement to genocide. That would be the easy thing to do.
The obviously very hard, and probably impossible, thing to do, but perhaps the morally correct thing to do, is to also urge that the UN Security Council, under a chapter 7 resolution, refer the situation of Iran and its incitement to genocide to the International Criminal Court for investigation and potential prosecution. That would be individual criminal liability for those involved in the incitement themselves. I think it's unlikely, given the vetoes in the Security Council and the complicated nature of what's going on, that this would be successful.
Then in between the easy and hard, there are multilateral efforts that can be taken in the Human Rights Council, in the General Assembly, to include language in the General Assembly resolution on the incitement question. That might be a challenge multilaterally. Given the large number of states that have continued to vote against that resolution on Iran, that might be untenable politically. But that is multilaterally, and, as I said, somewhere between the easy and the hard in terms of things that can be done.
