YaATW2KT: The Second Mexican-American War

[RN7]

The French Eryx ATGM might penetrate the frontal armour of an earlier M1 Abrams with a lucky hit, but not the M1A1. The Eryx was also used by Canada, Malaysia, Norway and Turkey,

According to Paul Mulcahy's page: The Eryx was also used during the Twilight War by the Swiss and Austrians, as well as special operations units of the US, Great Britain, Mexico, Israel, and Jordan.

Other missiles which might do a number on an M1

Franco-German HOT-2. The earlier HOT-1 was widely exported. The more powerful HOT-2 wasn't exported much until after the Twlight War period.

Soviet AT-14 Kornet. From Paul's page it was available from 1994. But I think it was probably kept with elite Soviet units in Europe.

Soviet AT-15 Springer: From Paul's page it was not in widespread as it was first used in the Ukraine in 1997. Again not likely to be sent to Mexico.

Soviet AT-16 Scallion: New air launched missile used by Su-25, Su-27 and latest Soviet attack helicopters (not Hinds). Not in widespread service.

Also the Hellfire (AGM-114L, K and L), the TOW-2B and C and the TOW-3 missiles could do the job.
