Frankly, she’s right. What you see countries like Canada doing is just as nationalist as what the US is doing, and the UK would be wise to stay out of it.

We need to stop this cascade of nationalism. Nationalism only leads to war. When countries are interdependent, they lose more than they gain through bloodshed. This is the only reason the past eighty years have been relatively calm, with wars only concentrated in places with little economic interdependence between aggressors.

Globalism, despite its faults, is the only true force for peace.
