Without the Texas Annexation, Gasden Purchase & Mexican Cession the U.S. would be smaller and less rich because California & Texas would not be a part of it & Mexico would be bigger and richer with them.
America would be smaller
the us would be smaller and still in war maybe today
there would be less land for us and more for mexicio
mexico would have more land and power to control
The US would be smaller.
mexico would be bigger then the us
there will be a war betwen tham
It would be really weird. There would be allot of states that wouldn't be apart of the United States like Arizona, Nevada, Texas, Utah etc.
