That is unless Mexico became a nuclear power in the Twilight 2000 timeline.
As far as I know Mexico has no nuclear weapons. I just have trouble imagining either the military of the civilian government saying to Mexico, "Go ahead, help youself to a piece of us." I think in peacetime if Mexico tried that now, they would meet with our conventional forces, and who knows we might just decide to annex the rest of Mexico, though I think that would prove to be more trouble than its worth. We would most likely occupy Mexico for a time and set up elections and leave. Occupying a piece of the US woul prove to be most troublesome for the Mexican government, a state that should be patting itself on the head for staying out of World War III would instead be incurring casualities trying to occupy a piece of the US. Not all American citizens would be completely passive and docile under Mexican rule. Some Mexicans would come back in bodybags and the Mexican politicians would have to explain why they are there. Mexico's defense budget would have to go up, and exports would be way down, the economy, to say the least, would be in trouble and Mexicans would want to know what they are there for? Some would no doubt say, "Ha ha, we got our land back!" but no doubt those aren't the people who put on the Uniform and deal with Americans under occupation and all the looks of hate they get as they perform their duty. Americans probably won't blow themselves up, but they are quite clever and educated and probably set up alot of nasty booby traps for the Mexican soldiers. The Southwest can become much worse than a Mexican Vietnam. Somehow the Mexicans have to win "Hearts and Minds" perhaps by rebuilding infrastructure, but that can't be cheap for a third world country like Mexico. The alternative is to rule with an "iron fist". Mexico is a democracy, so ruling with an "iron fist" will alarm some democrats in Mexico who reason that if Americans can be ruled with an "iron fist" so too could Mexican citizens. And there are the everypresent communist guerillas in the hills that could be used as an excuse.
The only problem is that Mexico can't nuke any US cities as they don't have any nuclear weapons.According to canon, not only did the US respond differently, so did everyone else. Nukes were used quite happily on the battlefield and against military and industrial targets but there was no widespread deliberate targetting of cities. Also, the US military was effectively in charge of any remaining nukes and soldiers, as a rule, tend to be far less gung-ho about nukes than politicians, so I doubt the US would have nuked any Mexican cities unless the Mexicans nuked a US target first.
