|North American Front|
|Date||1938 - 1943|
|Result||Decisive Allied victory|
Like Iran, the USA was cornered between two axis powers. (Its death toll in this war would be comparable to the USSR of OTL). The North American Front opened when Britain launched Operation Burgoyne in September 5 1938. 1.7 Million German, British and Canadian troops invaded the continental United States (neglecting Alaska lest they incur the Soviet Union's involvement). The invasion met with initial successes, annexing much of Washington State, Montana, North and South Dakota and northern Minnesota.
Battle of New York
However, the Americans put up a significant fight in The Battle Of New York (Hitler is an American---Version 1), leading to 2 million deaths on both sides and with a British defeat. During this battle, Himmler coaxed the Mexicans to invade Texas, New Mexico, Arizona and California, to relieve the overstretched Axis forces.
While fighting raged in the North, the Mexican navy was shredded by the US Navy. The only significant gains the Mexicans made were in Southern California. The main Mexican army was devastated at El Paso, Texas. General Eisenhower led his forces and pushed the Mexicans from Texas down into Mexico city itself within a year, forcing the Mexican president to sign the Treaty of Austin.
After the Battle of New York, things were looking up for the Americans, with the F-3 being rolled out from the Rockies alongside the new M26 Pershing tank. By early 1942, the Americans have pushed the Axis out of the USA and began pushing into Canada. It was during Operation Bald Eagle (Coordinated by Omar Bradley and George Patton) that Hitler's son William was shot down in his bomber over Canada by a pair of British Spitfires.
War in the Canadian Rockies The war in British Columbia was a distant affair, ignored in favour of the more titanic battles raging farther east. During 1940 and 1941, ferocious fighting between the small US and Canadian forces resulted in few gains for the former.
The final effort
Operation Hatchet, the drive to Winnipeg cut Canada in two. By July 4 1942, Most of Southern Canada, including Ottawa, was under US control. By the end of the war, only pockets in Quebec were still fighting on and it was from one of these pockets that the German nuclear missile was fired into Washington DC.
