YaATW2KT: The Second Mexican-American War

[castlebravo92]

For Context, the U.S. and Mexico had an incredibly difficult relationship to try to navigate.
1. As early as Andrew Jackson's presidency, the US offered to buy California. Mexico refused to even discuss the matter.

2. US admittance of Texas into the Union was another friction point.

3. Mexico welcomed US settlers into TX-up to a point. Mexican officials wanted some presence against Native Americans and lawless elements. American migrants such as S.F. Austin were glad to have the land, less then enthusiastic about observing the terms and conditions that came with the land.In particular, the Mexico Constitution at the time banned slavery. Americans came in huge numbers and brought slaves with them in direct violation of Mexican law which infuriated Mexican officials.

4. By the Polk Administration, President Polk was very aware of the potential of the China trade for both missionary and trade ties-San Diego was a potential port, naval base AND and possible end for a southern-route Transcontinental Railroad. One of the leading advocates of a southern route for the Transcontinental Railroad was Secty of War Jefferson Davis btw.

5. Candidly, Polk was willing to settle for dividing Oregon with Britain but more than willing to go to war with Mexico. When asked about this seeming contradiction, Senator Thomas Hart Benton put it best-"Because dear sir, Britain is so strong and Mexico is so weak." (His words, not mine).

6. Last but not least, an increasingly democratic America was a sharp contrast to autocratic Mexico under Santa Anna-there were also border disputes (Rio Grande vs. the Nueces River) and the question Mexican debts owed to the US and US citizens.

Just context from a historian and my .02 for background. "Alas, Mexico, so far from God and so close to the United States." -author unknown.

Almost completely off topic, but my wife is Mexican-American and we'll get into these debates on "whose land is it anyway" when the topic of immigration comes up. I make it a point to tell her that first Spain and later Mexico invited white settlers into Texas from America (and also Europe) because they were struggling to find Spanish or Mexican settlers dumb enough to settle Comancheria. The Comanches burned back the Spanish settlement line almost 1,000 miles back into Mexico except for some fortified towns like El Paso and San Antonio.

The short-lived Texas Republic was one of those improbable flukes of history. Fight the Texas revolutionary war 100 times, and the Texans probably lose 98-99 times out of a 100. Mexico was actually a well developed, well populated state in 1835, while Texas was a sparsely settled backwater frontier. Texas had no business beating Mexico.

Even when the US and Mexico went to war in 1845, a lot of Europeans thought the "professional" Mexican army built on the European model would make quick work of the rag-tag militia army of the Americans.

Literally, six flags over Texas

Y'all probably knew about this already, but in case you didn't, Six Flags is named that because the flags of Spain, Mexico, France, Republic of Texas, the CSA, and USA have flown over the state where the company was founded.

One thing to consider if that after TDM the countries outlined on maps no longer functionally exist. Federal power only extends as far as agencies and military units that recognize that authority. So Mexico and Force Cuba invading isn't so much resisted by the US government but a bunch of individual towns in the invaded states.

Additionally I imagine the situation in Mexico likely isn't too different than the US with MilGov, CivGov, and New America. Multiple factions in Mexico have different influence with different military units and relationships with Russia and Cuba. The force invading the US is just one of the power blocs in the country.

I would also posit that post-TDM the US southwest is going to have seen a massive wave of emigration. Deserts have a low carrying capacity. A lot of cities of the Southwest are impractical without a lot of fuel-intensive infrastructure.

So not only is the southern border not have a lot of coordinated defense but what people are left don't have a lot of resources available to defend against a moderately coordinated and cohesive force. That's even ignoring the heavy handed and draconian resource stealing by the USG.
