A humorous history of simmering tensions between the US and Canada from the War of 1812 to actual invasion plans drawn up by both sides.

It’s known as the world’s friendliest border. Five thousand miles of unfenced, unwalled international coexistence and a symbol of neighborly goodwill between two great nations: the United States and Canada. But just how friendly is it really? In War Plan Red, the secret “cold war” between the United States and Canada is revealed in full and humorous detail.

With colorful maps and historical imagery, the breezy text walks the reader through every aspect of the long-running rivalry—from the “Pork and Beans War” between Maine and Newfoundland lumberjacks, to the “Pig War” of the San Juan Islands, culminating with excerpts from actual declassified invasion plans the Canadian and US militaries drew up in the 1920s and 1930s.
