Retaliatory tariffs on yoghurt and whisky have been imposed by Canada. Will President Donald Trump up the ante? If he does, a 25 percent tariff on the products of Canadian singer Justin Bieber is urged.
Tensions with Canada date back at least to The War Of 1812. It is Ersjdamoo’s suspicion that a hidden cause of that war was a desire to grab Canada for the United States. (Background: Time To Grab Canada, Ersjdamoo’s Blog, July 4, 2018.)
During the War Of 1812, there existed what amounted to a total tariff upon all goods potentially coming into the U.S. from Europe. This virtual tariff was caused by a British naval blockade against us. What was the result of this form of ultimate tariff? At the end of the war, President James Madison addressed the U.S. Congress and stated:
But there is no subject that can enter with greater force and merit into the deliberations of Congress than a consideration of the means to preserve and promote the manufactures which have sprung into existence and attained an unparalled maturity throughout the United States during the period of the European wars. 
Britain was preoccupied with its fight against Napoleon Bonaparte. It was the perfect time, with Britain distracted, to annex Canada to these United States. Due to the Napoleonic wars and the British blockade, manufactures (factories) sprang into existence right here in the USA. Was James Madison saying, in effect, Who needs Europe? The war had demonstrated we ourselves could manufacture needed products.
And who needs China? What Thomas Jefferson scorned as a “hireling press” in his letter to the Marquis de Lafayette dated February 14, 1815 , is now called “fake news” by President Donald Trump. The hireling press is cranking out anti-tariff “news” 24/7, consequent to an emerging trade war with China. The hireling press, running dog lackeys for their globalist masters, can only paint one side of the picture. It never mentions the other side: manufactures which will have sprung into existence and attained an unparalled maturity throughout the United States.
