Unfortunately, I think you're right: Canada's importance internationally has indeed diminished. I think it started when the Harper government was in power and has continued under Mr. Trudeau's government, unfortunately.
It's important to understand that in the current context, international issues are closely linked to domestic issues. If we don't invest enough internationally, it can come back to haunt us.
In the past, Canada's diplomacy was very active, which was an added value, particularly appreciated by Washington. We were able to interpret the views of developing countries through our development assistance program, and we had a lot of influence in some African and Asian countries as well.
The fact that we haven't been invited to join the AUKUS alliance or other recently created forums may indicate that we're paying the price after years of neglect.
From a defence perspective, Canada clearly needs to invest more, particularly in the Canadian Arctic. Again, this has to be linked to China, which is very interested in the Arctic because of the fishery and mineral resources there. I would say that we are under‑equipped. Increasing our investments would be a way to demonstrate to NATO that we are serious about defending not only the North American continent, but that organization as well.
