It does nothing to improve sentiment. Personally until the U.S. goverment stops crying that Canadians (who the US has a trade SURPLUS with) are taking advantage of them (soft wood lumber comes to mind) I am shopping else where. I’ve always bought domestic cars my whole life, well I just bought a BMW made in Europe. My family has seen more of the U.S. then of Canada. No more. We took holidays in the U.K. So until the U.S. moves away from a “Me First” attitude when dealing with the international community they can suffer the consequences.  And as an aside the U.S. isn’t the only builder of military jets.
