Final answer:
The US should not have gone to war with Mexico to expand its borders in the 1800s due to violations of sovereignty, negative consequences, and increased tensions.
Step-by-step explanation:
I believe that the US should not have gone to war with Mexico to expand its borders in the 1800s. First, from a Mexican perspective, the US annexation of Texas and invasion of Mexican lands were seen as violations of their sovereignty, leading to a sense of injustice and resentment. Additionally, the war resulted in negative consequences for both Mexico and the United States. In Mexico, the war led to the loss of territory, dispossessed Hispanics of their land, and increased tensions between American and Mexican populations. In the US, the expansionist movement further ignited the debate over slavery. Overall, the negative consequences and impacts on both nations make it clear that the US should not have pursued a war with Mexico for expansion purposes.
