Yep I'm Mexico I'm just stating something I considered doing and I'm already having this discussion with the French:P Don't worry I'll be in league with you guys:)
The United States of Mexico does not condone the act of slavery but the recent actions by the Union have been incredibly hostile to a peaceful secession of the Confederate States of America. To economically and militarily try to strangle the Confederacy in order to force reunification is unacceptable. The United States of Mexico does not condone the actions of the Union but will not take any aggressive military actions remaining neutral. However the United States of Mexico shall openly engage in trade with the Confederacy and recognizes the legitimacy of the Confederate States of America as an independent country.
~Benito Juarez, President of Estados Unidos Mexicanos
