How was the Mexican American war a means to protect American interests

The Mexican-American War, which took place from 1846 to 1848, was primarily fueled by American interests in expanding westward and securing control over valuable territories. Here are a few ways in which the war was seen as a means to protect American interests:

1. Manifest Destiny: The concept of Manifest Destiny, which was popular in the 19th century, fueled the belief among Americans that it was their destiny to spread across the continent. This expansionist ideology led to a desire to acquire and control new territories, including those in present-day California, Texas, New Mexico, Arizona, Nevada, Utah, and parts of Colorado and Wyoming.

2. Annexation of Texas: The annexation of Texas by the United States in 1845 was a major trigger for the Mexican-American War. Texas had gained independence from Mexico in 1836, but Mexico disputed the annexation and considered Texas to be part of its territory. Protecting America's claim to Texas was a primary objective of the war.

3. Border disputes and territorial claims: There were ongoing disputes regarding the Texas-Mexico border, with the U.S. claiming the Rio Grande as the border and Mexico believing it to be the Nueces River further north. The war aimed to resolve this issue in favor of the U.S. and establish clear borders, protecting American interests and securing control over a significant territory.

4. Economic interests: The American government and private individuals had significant economic interests in California and other parts of the Southwest, such as access to trade routes, valuable natural resources, and potential agricultural land. The war provided an opportunity to seize and control these economically important regions.

5. National security concerns: Some proponents of the war argued that the Mexican government posed a threat to American national security. They believed that a military intervention in Mexico would prevent any potential threat from taking hold and protect American interests by ensuring stability and control over the region.

It is important to note that while these reasons were used to justify the war, there were also debates and strong oppositions within the United States regarding the motivations and ethics of the conflict.
