From BrianMcCandliss:
"All evidence indicates conclusively that the Civil War was nothing but a trumped-up use of force against sovereign nations, by simply claiming that they weren't such...."
So, if the United States is not a "nation", and never was, it had no right to go to war with Mexico, or sign a treaty which ceded land from Mexico to the United States. So...California, your state, is really still part of Mexico.
Adios, amigo! (I meant "amigo" in a rhetorical sense. But we all know you claim to be really smart...so you probably knew that.) (What is your degree in again?)
