The United States military developed the War Plan Red – or “Joint Army and Navy Basic War Plan – Red” – in the 1920s. The detailed Plan Red was augmented and amended in the 1930s. It envisioned the invasion of Canada by the United States to hurt the interests of the United Kingdom. Later, Plan Red called for the US military to invade Bermuda and Britain’s Caribbean assets. Australia and New Zealand were singled out as British allies and enemy powers.
The document was declassified in 1974. It was only the last of many such color-coded contingency war plans.
“Invading Canada is an old American tradition. Invading Canada successfully is not.” See more Canadian response to War Plan Red.
