United States Top Secret Plan to Attack Britain & Canada !

Despite fighting on the same side as Britain at the end of World War I, in the 1920's and ’30's the US drew up several plans for wars against other countries—even the British Empire. The plan included an invasion of Canada, use of chemical weapons, and a naval blockade of Britain herself. The scenario that would have led to war was predicted to come about due to a trade disagreement. If the plan had gone ahead, US troops would have occupied any colonies captured in the event of a peace agreement. War Plan Red first set out a description of Canada's geography, military resources, and transportation, and went on to evaluate a series of possible pre-emptive American campaigns to invade Canada in several areas and occupy key ports and railways before British troops could provide reinforcement to the Canadians—the assumption being that Britain would use Canada as a staging point. The idea was that the American attacks on Canada would prevent Britain from using Canadian resources, ports, or airbases.
A key move was a joint U.S. Army-Navy attack to capture the port city of Halifax, cutting off the Canadians from their British allies. Their next objective was to "seize Canadian Power Plants near Niagara Falls."[5] This was to be followed by a full-scale invasion on three fronts: From Vermont to take Montreal and Quebec, from North Dakota to take over the railhead at Winnipeg, and from the Midwest to capture the strategic nickel mines of Ontario. In parallel, the U.S. Navy was to seize the Great Lakes and blockade Canada’s Atlantic and Pacific ports.
