There are two things.
One thing that I thought was very well done in the DPU is the description of where the world is in terms of the risks. I think, on that level, it's very well presented.
With regard to Ukraine, I think it's really fundamental that we all recognize that if Ukraine loses, the world is a much less safe place in the future. This is because it tells those who are seeking to disrupt the status quo that it can be done in imperial ways, just by taking over your neighbour if you see fit, and that no one is necessarily going to hold you to account and push you back.
With the first war in Iraq, when they tried to invade Kuwait, there was a sense that the world would not tolerate annexation in this way. Even though the Americans went to Iraq years later, there was never a sense that Iraq would become an American state. It was not a war of annexation.
Once you start allowing that to happen, it gives other states a lot of ideas. I don't think we want to live in that world, and I think Canada has probably the most to lose as a medium-sized player in a world that doesn't have rules.
