Episode 91: The Canadian Plan to Invade the United States

For hundreds of years, Canada and the United States have been each others closest neighbours, strongest allies, and largest trading partners... except for all the times they were at each others throats. The Revolutionary War, the War of 1812, the Pork and Beans War, and the Pig War -- 50% actual wars, 50% backwoods hijinks. This past is one far more recent than one might think, including two declassified documents from the early 20th century -- Defense Scheme One and War Plan Red.
