Can it be done? Nothing is off the table. Weaker/incompetent America, stronger/competent Mexico, alliance with a European empire, your choice.
"Fifty-four Forty or Fight" turns into the United States having to fight both the Britian and Mexico at the same time. I am not sure the United States makes this "mistake".
This is one I've always been very interested in. But I want to see, how Mexico becomes more stable, not just take it as a given that happened to get that way somehow, and therefore they can win. I guess I'm more interested in the process of attaining stability than I am in the war. Not really a military history person.Stable Mexico, Rebuilds it's economy, Strong Army and Navy, I think that's what you need at most
Yes, this is really the interesting part. A starting point, if you don't want to go with a pre-War of Independence POD, is to have a better Victoria presidency. In OTL he did create a merchant marine and established the military academy. Perhaps he could reject Lucas Alamán's proposal of expelling all the Spaniards, which did happen in OTL and severely affected the country's economy, as well as trying to reduce the influence of the masonic lodges and the army. This could perhaps enable Gómez Pedraza to assume the presidency without being deposed by Guerrero and prevent the "new president every other month" that was so prevalent in Mexico during the 19th century and therefore laying the bases for much stronger institutions.This is one I've always been very interested in.

Of course in OTL. Never say never in ATL. What if the British forced it and gave the US not choice? Or someone in Britian decided to force the issue because the US was in a war with Mexico?That was only ever a slogan and not something Washington would have instigated a war over, certainly not concurrently with a war in Mexico.
