Was the United States justified in going to war with Mexico?” This is a trigger phrase similar to watching two brothers argue over who gets to play Xbox. “It's MY Xbox.” “But you ruin the whole game.” In this case, Mexico owns the disputed land and the United States is eager to take it. In my opinion, the United States should not have gone to war with Mexico for these reasons: the United States caused the war; conquering Texas was another way to spread slavery; and annexing Texas would make America an even bigger threat, scaring Mexico along with other countries. The “US invasion” was just part of the US plan to conquer lands in the early 1800s, again under the same excuse, manifest destiny. Mexico's idea of ​​convincing American colonists to move there to level out the contrasting social population of rich and poor failed... and soon after gaining independence from Spain - a Mexican horror story!

(Doc. C)" From Mexican perspectives, the border between Mexico and the United States was the Nueces River. When the Americans crossed the Rio Grande, which was below the Nueces River, Mexico caught fire. This means that the United States started the war, forcing the Mexicans to backfire until they finally had to start defending themselves. “Polk saw the way Mexico treated [the envoys] as an opportunity [to go to war]. He felt that America's honor had been called into question. When the news arrived…that Mexican soldiers had opened fire on Americans on the “Texas side” of the Rio Grande, President Polk had a reason to go to war (BE).” I think this is full of nonsense because previously the quote implied that the US had a reason to go to war, so why would Mexico attack first? This unlikely event suggests some elements of change in the history of the war. “A current of emigration from the United States soon followed. Slave owners crossed the Sabine (river between Louisiana and Texas) with their slaves, in defiance of the Mexican Freedom Ordinance. (Doc. D)” This quote makes the United States seem very ironic since the United States was “the land of opportunity and freedom” where many people of ethnic groups rushed to, but many slaves had no opportunities nor freedom. In Mexico slavery was illegal, so in some ways Mexico was even freer than the United States. The Mexican-American War was just another product of Manifest Destiny, an excuse by “God” to conquer lands from the Atlantic to the Pacific to spread “democracy” which eventually turned into an excuse to spread slavery. If Americans took control of Texas (which happened anyway), the territory would go back to where it started: slavery. Considering the fact that Texas was still theirs, Mexico sought to prevent opposition to slavery from becoming obsolete. “The combination of American troops on the Rio Grande and the attempt to purchase much of their country angered the Mexican government. [Polk's envoys] were asked to leave Mexico City (BE).” The ease with which the author mentioned the fact that the envoys were asked to leave may suggest that the United States does not want to admit that it seems like a bad person. That is.
