I just have to weigh in. We've talked about diplomacy. Diplomacy also comes from strength. You talk about the economic factors and all of these. It's not about economics. It's about how we have Canadian security.
We also seem to be fixated on this one scenario that is just about the North Koreans firing a missile at North America before anything else happens. I think we have to be really careful about getting so fixated on that, because the more realistic probability is a quick invasion from the North Koreans into South Korea and a war erupts. At that point, we want to make sure that we are participating fully with the Americans when the heat of battle means that all the planning we had beforehand goes out the window.
Therefore, in answer to your very good question—what is the cost if we're not involved?—it's that in that scenario where North Korea invades South Korea, the war breaks out, things get hot, and then at that point they fire, we want to be ready in some form, even if it's as a junior participant that we're there. To say that somehow we have security by not participating I think is totally based on false premises, to be honest.
