when you run a country like a business, or an empire, allies are not to be upheld for similar values and customs but treated as competitors that need to be absorbed through shady stock deals, or through hostile takeover bids. and, the more friendly they are, the easier they are to conquer.
meanwhile, dissimilar countries and flat out enemies are to be ignored, as they aren't invading the market share.
it's a backwards idea, all around. and, if nothing else comes from it, let us hope that the boneheadedness of trump puts an end to this "run a country like a business" thing once and for all.
"punishing canada" is not likely to go over well with anybody at all.
