Canada is a trading country. Land Mass is second largest on Earth Planet extending from above the North of the Arctic Circle to a West to East coasts border with the United States of America to the South.
In earlier growth it has benefitted from easy to mine mineral resources which are still available to trade but depleted
A populist reaction by D. Trump today is the planned cancellation of United Nations World Health Organization (UNWHO) support. Donald seeks re-election & depends in part on poll support of a populist base who see recent UNWHO action a anti USA.
Myself I see earth public best served by becoming more involved in UNWHO affairs & if wrong is perceived attempting to correct. Not the Donalds of this world where reaction is what is seen as personal interest.
Resulting from Canada having the second largest land area on earth planet stretching from more Northerly than the arctic circle to the USA border in the South plus being a primary trading country then Canada has a major security component in comparison to population.
