Although it is not my historical strongpoint, I have been wondering what the butterflies would have been if the Mexican-American War would have ended differently than it did OTL.
Basically, would there be any PODs that would lead to the northern Mexican territories (Baja California, Sonora, Nuevo Leon, etc.) becoming a part of the United States? How would that change history?
And no, I'm not trying to act like Turtledove or pull an Ameriwank.
