On more than one front, the current occupants of the White House could benefit from a study of history.  What new facts do they now possess that have not been known to them for decades and rejected repeatedly?  This latest softwood trade volley by the US is what it has always been, a means to temporarily enrich US lumber companies and their litigators until the facts prevail yet again.  This situation is most certainly a political calculation that "Blaming Canada" will obscure the current administration's inability to deal with the more serious trade and economic issues that face America.  Unfortunately, the big losers in this game are US home builders and consumers.
