Playing as the Allies, the course of history goes the way it actually did with the Battle of Normandy sealing Germany's fate and the capture of Iwo Jima and Okinawa sealing Japan's.
The campaigns interchange between the armies of Great Britain, Russia, and the United States of America as time progresses throughout the years of 1939-1945.
Playing as the Axis leads to an alternate history, basically with what-if scenarios, which begins with a tactical German victory at Crete.
Having driven out British forces in the Mediterranean, Rommel and his Afrika Korps win the Battle of El Alamein, pushing the British all the way back through the Suez Canal.
With the fuel-rich Middle East in German hands, Germany wins the decisive Battle of Stalingrad and the following year, the endlessly supplied Panzer units crush the Russians at Kursk, effectively sealing the fate of the Eastern Front.
Meanwhile in the Pacific, Japan manages an invasion of Australia, leaving the Americans without a staging area in the Pacific (it is also suggested that the attack on Pearl Harbor was more successful, with the fleet being sunk in deep waters rather than in the shallow waters of the base).
The Battle of Normandy still happens; however, the landing beaches have unfavorable terrain and the Germans' counterattack is successful.
The failed invasion at Normandy not only prevented the Allies from opening a new front in the war, it also oversaw Germany's plans to invade Great Britain.
With Rundstedt invading from the south and Rommel invading from the west, Operation Sea Lion proved to be a success, forcing the British to surrender.
While Germany deals with partisan resistance, Japan invades India to crush the last of the British forces under the command of Wingate.
With Great Britain defeated, Germany is able to turn its attention back to Stalin and the Soviet Union.
Japanese advance units under General Kuribayashi and German Panzer divisions under Field Marshal Manstein surround Moscow, but the battle for control of the city turns into a three way brawl with German and Japanese units each vying for control of the city.
The battle ends in a German victory.
By now, the United States of America is the only Allied nation left to challenge the Axis.
With the defeat of British and Australian forces, Japan quickly eliminates the last remaining ships of the American fleet and captures Midway, and later Hawaii.
With American naval forces crippled beyond repair, the Allies lose their chances of defeating the Axis Powers and America settles into a new Cold War with Japan in the Pacific and Nazi Germany in Europe. 
The Attack on Panzer Group West's headquarters at La Caine in Normandy was a successful airstrike by the RAF's Second Tactical Air Force.
The raid took place on 10 June 1944 and knocked out German control of its armoured forces.
The attack resulted in the wounding of the Panzer group commander General Leo Geyr von Schweppenburg, the breakdown of German communications and the withdrawal of the HQ to Paris. 
Factors that influenced the boundary.
The German military spoke up for control of the Alsace region, up to the Vosges (mountain range) and the area between Thionville (Diedenhofen) and Metz as a requirement for the protection of Germany.
Most importantly, the German military regarded control of the route between Thionville and Metz as the most important area of control if there were ever to be a future war with France. 
Adolf Hitler was greatly influenced by the psychological tactics of warfare the British had employed during WWI, and attributed the defeat of Germany to the effects this propaganda had on the soldiers.
He became committed to the use of mass propaganda to influence the minds of the German population in the decades to come.
Joseph Goebbels was appointed as Propaganda Minister when Hitler came to power in 1933, and he portrayed Hitler as a messianic figure for the redemption of Germany.
Hitler also coupled this with the resonating projections of his orations for effect.
At the start of the Second World War, the British set up the Political Warfare Executive to produce and distribute 'black' and 'white' propaganda (see Categories of psychological warfare section for definitions).
Through the use of powerful transmitters, broadcasts could be made across Europe.
Sefton Delmer managed a successful black propaganda campaign through several radio stations which were designed to be popular with German troops while at the same time introducing news material that would weaken their morale under a veneer of authenticity.
British Prime Minister Winston Churchill made use of radio broadcasts for propaganda against the Germans.
During the War, the British made extensive use of deception – developing many new techniques and theories.
The main protagonists at this time were 'A' Force, set up in 1940 under Dudley Clarke, and the London Controlling Section, chartered in 1942 under the control of John Bevan.
Clarke pioneered many of the strategies of military deception.
His ideas for combining fictional orders of battle, visual deception and double agents helped define Allied deception strategy during the war, for which he has been referred to as "the greatest British deceiver of WW2".
During the lead up to the Allied invasion of Normandy, many new tactics in psychological warfare were devised.
The plan for Operation Bodyguard set out a general strategy to mislead German high command as to the exact date and location of the invasion.
Planning began in 1943 under the auspices of the London Controlling Section (LCS).
A draft strategy, referred to as Plan Jael, was presented to Allied high command at the Tehran Conference.
Operation Fortitude was intended to convince the Germans of a greater Allied military strength than existed, through fictional field armies, faked operations to prepare the ground for invasion and leaked information about the Allied order of battle and war plans.
Elaborate naval deceptions (Operations "Glimmer", "Taxable" and "Big Drum") were undertaken in the English Channel.
Small ships and aircraft simulated invasion fleets lying off Pas de Calais, Cap d'Antifer and the western flank of the real invasion force.
At the same time Operation "Titanic" involved the RAF dropping fake paratroopers to the east and west of the Normandy landings.
The deceptions were implemented with the use of double agents, radio traffic and visual deception.
The British "Double Cross" anti-espionage operation had proven very successful from the outset of the war, and the LCS was able to use double agents to send back misleading information about Allied invasion plans.
The use of visual deception, including mock tanks and other military hardware had been developed during the North Africa campaign.
Mock hardware was created for "Bodyguard"; in particular, dummy landing craft were stockpiled to give the impression that the invasion would take place near Calais.
The Operation was a strategic success and the Normandy landings caught German defences unaware.
Subsequent deception led Hitler into delaying reinforcement from the Calais region for nearly seven weeks. 
Albert C. Wedemeyer was born on July 9, 1897, in Omaha, Nebraska and was a graduate of Creighton Prep High School.
In 1919, he graduated from the United States Military Academy at West Point.
As a U.S. officer, he was appointed to the German war college Kriegsakademie in Berlin, 1936-38.
Wedemeyer was included in 1938 German maneuvers, which gave him unique insight into German tactical operations.
When he returned to Washington, in 1938, Wedemeyer analyzed Germany's grand strategy and dissected German thinking.
Wedemeyer thus became the U.S. military's foremost authority on German tactical operations, whose "most ardent student" was George C. Marshall.
Wedemeyer was greatly influenced, and his career aided, by his father-in-law, Lieutenant General Stanley Dunbar Embick, who was at that time Deputy Chief of Staff and Director of the War Plans Division.
At the outbreak of World War II, Wedemeyer ranked as lieutenant colonel and was assigned as a Staff Officer to the war-plans division of the United States War Department.
Notably, in 1941 he was the chief author of the Victory Program, which advocated the defeat of Germany's armies in Europe as the prime war objective for the U.S.
This plan was adopted and expanded as the war progressed.
Additionally, Wedemeyer helped to plan the Normandy Invasion.
