Trump's technique, from the "Art of the Deal" is to keep things noisy, a little threat here and there, use fake press to test the waters or spook an opponent.

We have a bit of retaliation on American liquor, many provinces no longer buying any. So the producers are squawking and sales way down. Not sure if that will change as they demand we let them in to sell booze.
