Pro: The War Was Justified
Proponents of the war's justification might argue that President Polk's attempt to purchase the land demonstrates a reasonable and diplomatic approach to territorial expansion. The refusal of the Mexican government to engage in negotiations could be seen as an obstinate rejection of peaceful resolution. Ultimately, supporters may contend that the U.S. had a right to defend its interests and secure the territory it sought after being rebuffed diplomatically.
Con: The War Was Not Justified
Opponents could argue that President Polk’s willingness to use military force after a failed diplomatic attempt reflects an aggressive expansionist policy rather than genuine intent to acquire land peacefully. The war could be deemed unjustified as it led to significant loss of life and suffering, and critics may contend that the U.S. was seeking to impose its will on a neighboring country instead of respecting its sovereignty. This stance highlights the ethical implications of waging war for territorial gain.
