[Turtledove] How would the WorldWar series have progressed if The Race had tried to conquer the Southern Victory/Timeline-191 version of Earth?

The "Alternate Point of Departure" is still sometime between December 1941 and May 1942, which places the arrival of the First Fleet sometime during the events of *Return Engagement* or *Drive to the East* from the *Settling Accounts* series.

In the Southern Victory series, the CSA and USA fight multiple wars that only end when the CSA surrenders and ceases to exist in 1944. Now we ought to expect The Race would carry out landings worldwide, including Confederate Florida, Unionist Illinois, Unionist Idaho, and Unionist New York in North America, which would further destabilize the North American theater of the Second Great War as both Union and Confederacy have to scramble to contain the beachheads of the Lizards inside their own territories.

The Race could easily become a 'deus ex machina' (like the original POD of Timeline-191) that would distract the United States from its long-term campaign to finally reconquer the Old South. How ironic it would be, if this second POD was instrumental in saving the Confederacy from its destined destruction, once again.

The Lizards only recognized the Not-Empires when they showed they had nuclear arms. All the radiation was gonna muck up the whole planet, and the Emperor doesn't send space armadas for nothing.

I would think that the CSA wouldn't have been able to develop the nuclear technology and would have either been conquered along with Mexico, or ended up as a buffer state similar to Poland's fate.
