In what ways was the Mexican American war justified

There are different perspectives on the justifications for the Mexican-American War from different historical, political, and cultural viewpoints. Some of the arguments made to justify the war include:

1. Manifest Destiny: The idea of Manifest Destiny, which was prevalent at the time, claimed that the United States had a divine right and duty to expand its territory from coast to coast. Proponents argued that the war was necessary to fulfill this destiny and bring civilization to the Mexican territories.

2. Annexation of Texas: Texas was an independent republic before it was annexed by the United States in 1845. Mexico disputed the legitimacy of its independence and claimed Texas as its own territory. Supporters of the war argued that it was necessary to protect and defend Texas against Mexican claims.

3. Mexican government instability: Mexico was experiencing political instability at the time, with frequent changes in government and leadership. Some argued that the United States had a duty to intervene militarily and promote stability in the region.

4. Border dispute: There was a dispute over the border between the United States and Mexico, with both sides claiming different territories. The war was seen by some as a way to establish a clear and recognized border, settling the disputes between the two nations.

5. National security and defense: American politicians and military leaders argued that the war was necessary for national security and defense. They claimed that Mexico's unstable government and potential alliances with European powers could pose a threat to the United States in the long run.

It is important to note that these justifications reflect the arguments made at the time and may not necessarily be seen as justifiable or ethical from a modern perspective. The war led to significant loss of life and land for Mexico, and it also sparked controversy and criticism both domestically and internationally.
