Nah. It would be more like our 51-62 states. Mexico is composed of multiple states, at least one of which was in open rebellion not to long ago.
Annexing Mexico would be a VERY bad thing.
It would be much better to build a wall, complete with mine fields and machine guns - sort of an inverse Berlin Wall.
It would be our 51st through 82nd IIRC. I think Mexico has 31 states.
I agree - it is not just the politicians who are corrupt, it is the population in general.
I'd annex Cuba before Mexico.
.....Annexing Mexico would be a VERY bad thing....
The wall is a lost cause. The best option is to conquer Mexico again and treat it as a conqured territory. Abolish the existing government and imprison all the politicos for 5 years or so. Set up and maintain a military government for 10 years with local elections at 5 years.
Sell the oil business and all quasi national industry. Impose heavy taxes on workers who are illegals in the upper Estados Unitos.
Until the Aristos are exterminated as a political force there will be no peace and a wall is worthless.
