Was The Mexican-American War Justified?

When Mexico gained its independence from Spain in 1821, a string of ruthless dictators and weak presidents made Mexico an easy target for its powerful neighbor, the United States. The US swooped in to expand its territory and its popular institution of slavery. By doing so, the US started a war with Mexico that was justified for illegitimate reasons. The Mexican-American War was not justified because the US took Mexico’s land for the expansion of slavery, and justified their taking advantage of Mexico when it was politically weak by hiding behind Manifest Destiny.
The US wanted to expand its territory for the growth of slavery, which was a dehumanizing and morally wrong practice. Although many Americans wanted slavery to expand, many did not.

Jesús Velasco-Márquez, a modern-day Mexican professor of studies wrote an article in 2006 about the Mexican-American War. He said, “US historians refer to this event as ‘The Mexican-American War’, while in Mexico, we prefer to use the term ‘The U.S. Invasion...From Mexico’s point of view, the annexation of Texas to the United States was inadmissible for both legal and security reasons. ’’’ (Velasco-Márquez, 12). During the time of the independence of Texas, Mexico was ruled by the dictator General Antonio López de Santa Anna. Since the Mexican people were not able to vote when Santa Anna gave away Texas, they felt as if the US took advantage of them when Santa Anna was president. Mexico did not see the war as a dual sided conflict. To Mexico, the war was an invasion of the weaker by the stronger, and at a time when Mexico was vulnerable

The US did not not have solid reasons to do so besides their own greed, so the US hid behind the idea of Manifest Destiny and tried to justify their actions. John O’Sullivan was the New York City journalist who coined the term Manifest Destiny. He said, “Imbecile and distracted, Mexico never can exert any real government authority over such a country…’’ (O’Sullivan, 8). O’Sullivan and the US suggested that Mexico “needed” the US to come and take over, because otherwise Mexico was going to fall apart. Although this was somewhat true, the US did not try to help Mexico through this difficult time; instead, the US took advantage of Mexico’s weakness and tried to take over completely. The idea of Manifest Destiny was centered around the idea that God wanted the US to expand as much as possible because the US had a superior way of life. The US justified their cruel actions towards Mexico because they were “destined” to act accordingly. If Americans truly believed that all people were created equal, then Manifest Destiny was not a plausible idea. Manifest Destiny created a hierarchy system in which the US was on top; a hierarchy was the opposite of a society or world where all people were created equal. Therefore, the US did not have such superiority to Mexico that God thought it was acceptable for Americans to act like they were allowed to trample on Mexico’s government
