Canada has a population of roughly 40 million.

The U.S. has a population of roughly 340 million.

Canada is primarily an exporter of natural resources and food products.

The U.S. is primarily an exporter of WMDs and war matériels.

Don't ask them about circular trade.
A exports steel to B.
B builds agricultural gear and export to C.
C grows wheat and exports to A.
