I think that the current circumstances provide fertile emotional soil for that to grow. If countries like Canada could take it up as something worth pursuing, I do think that they will have some reception.
Of course, I'm not guaranteeing that. You know what happens in these wars. At some point, the shooting will stop and then people will quickly want to move this behind them. At that stage, those countries who may want to do what they want to do in the future may be against that sort of proposal, knowing that it may come back to haunt them.
This is now the time to move that project, if we think it is something that victims in this war in Ukraine or victims in other wars of aggression happening around the world as we speak could use.
