Talk of trade wars and retaliation make good copy but they don't make good sense in my opinion. Friends negotiate, they don't retaliate.
Emotional press conferences are not going to settle the issue. Canada needs to come back to the table. We need to close the door, roll up our sleeves and negotiate as need be, with good faith, and bring finality to it.
I would submit to you that showing of good faith is there. It doesn't get any clearer than that -- the commerce department's recent decision to slash the tariffs, to render a decision that would result in the elimination of tariffs probably as early as January.
