Previous- America joins the Allies
Sparked off by an accidental skirmish at the border, the Democratic Alliance launches a full invasion of the Soviet Union in 1941. First striking South, to the Iberian peninsula, they liberate it, then go around, through Africa, to hit Italy in the South. Despite stiff resistance, they force their way north, capture Rome, and then smash into Switzerland, capturing Zurich and Geneva within days.
There the good news ends. Mere hours after the capture of spain, the USSR initiates a massive vengance campaign against France. The French, fighting for every inch, are forced back down to a small area consisting just of Brest, Quimper, and Morlaix. As the Allied armies sweep West, to save the French, the Soviets get ever closer, capturing Morlaix after a 2 month struggle and then besieging Quimper. If Brest falls, then the war is over; the majority of Allied armies will be trapped deep in enemy territory, with no way out. But the British are under going attacks to Norwich. If they help, there is a chance the USSR will get a foothold in England, and that would be disastorus.
