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<em>War Plan Red</em>, the secret &quot;cold war&quot; between the United States and Canada is revealed in full and humorous detail.<br><br>With colorful maps and historical imagery, the breezy text walks the reader through every aspect of the long-simmering rivalry—from the &quot;Pork and Beans War&quot; between Maine and Newfoundland lumberjacks, to the &quot;Pig War&quot; of the San Juan Islands, culminating with excerpts from actual declassified invasion plans the Canadian and U.S. militaries drew up in the 1920s and 1930s. A perfect gift for history buffs (and Canadians and Americans alike),<em>War Plan Red</em> offers up a new wrinkle in the ever-evolving history of North American continental relations.
