What are significant details about the Mexican American war that would justify it

The Mexican-American War was a conflict that lasted from 1846 to 1848 and resulted in significant territorial gains for the United States. Justifications for the war from the American perspective include:

1. Annexation of Texas: Following the annexation of Texas by the United States in 1845, Mexico disputed the boundary of Texas, claiming it to be the Nueces River. However, the United States claimed a more southern boundary, the Rio Grande. Therefore, the clash over the border sparked the initial hostilities.

2. Border disputes and invasion: American President James K. Polk ordered General Zachary Taylor to move U.S. troops to the disputed territory between the Nueces River and the Rio Grande. Mexican troops had already been stationed and considered the presence of American troops as an invasion. This led to armed conflict and further worsening of relations.

3. Mexican debts and compensation: The United States claimed that Mexico owed American citizens significant debts that had been unpaid or not properly compensated for due to civil unrest in Mexico. The unresolved grievances created additional tensions in an already strained relationship.

4. Mexican instability and desire for territorial gains: The Mexican government was facing internal conflicts, unstable leadership, and regional revolts, which made it appear weak in the eyes of American expansionists. Some Americans saw this as an opportunity to acquire more Mexican territory, including California and New Mexico.

5. Manifest Destiny: The concept of Manifest Destiny, the belief that it was the United States' destiny to expand its territory from coast to coast, fueled American aggression towards Mexico. Many proponents of expansion saw the Mexican-American War as a necessary means to fulfill this vision.

6. U.S. desire for resources and trade access: The acquisition of territories like California would provide the United States with valuable resources, including gold, silver, and fertile land. Additionally, controlling Pacific ports in California would give the United States better access to trade with Asia.

It is important to note that the Mexican-American War is a complex and controversial event, and the justifications provided above may be viewed differently from the Mexican perspective or by those critical of the war.
