Based on what you describe, I would say they aren't headed in the wrong direction, but Canada is not alone.
I agree with you wholeheartedly that each of these factors—the rise in geopolitical conflict, isolationism on the part of some of the great powers in the world, the complete undermining of the international rules-based legal order and so on—can be looked at in isolation of one another, and they must not be. Our foreign policy needs to be well-rounded in order to understand that, if we're going to pour money into defence, at the end of that is war, and at the end of war are the internally displaced and refugees. Inevitably, the “problem” or “burden” that needs to be shared, as UNHCR calls it.... The refugees will come back to us. All of these things are connected.
