Why didn’t the United States take all of Mexico after the Mexican American War was won?

After the Mexican American War was won, some Americans at the time thought it would be a good idea to take all of Mexico, but most were happy to only take half.

The original goal had been to open a continental path from coast to coast, and that goal had been accomplished.

Why drag out the war longer, trying to subjugate a rebellious population? It would seem too much like brute aggression. One American newspaper proudly declared, “We take nothing by conquest. Thank God.”

“We never crossed a border. The border crossed us.” Saying of Tejanos (Texans of Mexican origin)
