had the french not invaded mexico under pretence of debt collection (i think) what would have it taken for the mexicans to intervene in the civil war? and on which side? would they go for california or texas?
I believe that the Mexicans actually went to Montgomery Alabama before the Battle of Fort Sumter and tried to do a deal with the Confederates but were turned away. I also seem to remember that very early on Davis and his government were drawing up plans for future expansion into Mexican territory...though I might be wrong on this.
And much of the impetuous for this war (and the strife in Texas) came from southern Democrats (including Polk) filled with notions of racial superiority and eager to expand slavery westwards. This was an attitude carried over by the Confederate leadership who had designs on seizing much of northern Mexico - primarily for the mines of Chihuahua and SonoraIf and I do mean If, as I don't think its plausible, I would say that Mexico would be more likely to aid the Confederate States. After all the United States had beaten the Mexicans fairly recently in world-historical terms and the U.S held more land and better land (California, New Mexico, Nevada, Utah....) with more useful resources that were once Mexican rather than the CSA which held only Texas and some part of Arizona (if memory serves me right)
