I don't know if this was asked or analyzed earlier but after reading Bulnes' "the greats lies of our history", what would happened if the mexican government enforces the antislavery laws on Texas in 1829, and also enact a new colonization law for admiting only colonial inmigration without slaves?
Bulnes' argue that in 1830 México has a decent navy, ( for an American country) , a well paid army of at least 30000 men with the same state of the Art arms and artillery as the US, the church has all is assets (during the next 6 years they spend all this contractic mercenarios for fighting the liberals) an also has 3 competent generals who doesn't have political ambitions: Manuel Mier y Terán, Felipe de la Garza and José Joaquín de Herrera.
Bulnes doesn't say that those elements could imply a Mexican victory, but could have been an honorably defeat, with less territorial loses and could triggered a civil war in the US in the elections of 1840, or even earlier on 1836 or 1832...even he said that in 1830 México could sell the norther half of Texas to GB in exchange of their involvemt in the war..
bulnes said that by 1830 the US doesnt exist as a hole country but by 2 different countries the proslavery south and the industrial north, the desunited States only united by the compromises of 1787 and 1820.
What do you think? What would be the implications of a 1830 mexican-American war over Texas??
