I think it could work with its allies. I think it would require a multilateral effort. Canada could not set up this kind of tribunal alone, and it would be most legitimate if it had the buy-in of both Israel and the Palestinian Authority in order to create this. Hybrid tribunals are best created when the parties to a conflict themselves accept it.
Again, I think that justice and peace negotiations have not been in the equation in this conflict. Whether it's a hybrid court, the ICC, universal jurisdiction prosecutions or the International Court of Justice, whatever it may be, this is the kind of conflict where justice deserves a chance.
