President Trump has made more threatening sounds about Canada than about Russia. He is wielding a weapon — sweeping 25% tariffs — that would almost certainly drive our Friendly Neighbor to the North into a recession, while he is making its leaders and people honestly fearful of the United States.

President Trump was handed a great economy, “The Envy of the World,” according to financial media. His trade war, lack of coherent economic policy and perhaps low interest in governing when cameras aren’t present have investors close to panic. The Dow Jones Industrial Average has lost more than 2,000 points since Election Day.

Economic roller coasters can be scary, but like the rides at the fair, the end produces satisfaction, relief and even a thrill. So, hang on.
