Question 1: Justification for the War with Mexico
-
“Mexico has passed the boundary of the United States, has invaded our territory and shed American blood upon the American soil. [Mexico] has proclaimed that hostilities have commenced, and that the two nations are now at war” (President James K. Polk, 1846).
- Claim: Justification based on the idea of self-defense and protecting American territory.
-
“Polk started out by trying to buy the land. He sent an American diplomat, John Slidell, to Mexico City to offer $30 million for it. But the Mexican government refused to even meet with Slidell” (PBS.org, n.d.).
- Claim: Suggests justification based on failed diplomatic attempts and the refusal of Mexico to negotiate.
-
“Yes: Mexico must be thoroughly chastised [punished]! Let our arms now be carried with a spirit which shall teach the world that…America knows how to crush, as well as how to expand!” (Walt Whitman, 1846)
- Claim: Justification under the belief of national pride and a desire for expansion.
-
“Polk and others saw the acquisition of Texas, California, Oregon, and other territories as part of the nation’s Manifest Destiny to spread democracy over the continent” (NCC Staff, 2023).
- Claim: Justification based on the ideology of Manifest Destiny and the desire to spread democracy.
Question 2: Arguments Against the War with Mexico
-
“...I more than suspect already, that [Polk] is deeply conscious of being in the wrong; that he feels the blood of this war, like the blood of Abel, is crying to Heaven against him…” (Abraham Lincoln, 1848).
- Claim: Suggests the war is morally wrong and highlights the moral responsibility for the conflict.
-
“…Ulysses S. Grant…would later call the war ‘one of the most unjust ever waged by a stronger against a weaker nation. It was an instance of a republic following the bad example of European monarchies, in not considering justice in their desire to acquire additional territory’” (PBS.org, n.d.).
- Claim: Argues the war is unjust and comparable to the actions of colonial powers.
-
“It is certainly not a popular war…its real object, the extension and preservation of slavery, no intelligent man honestly doubts…” (William Lloyd Garisson, 1847).
- Claim: Suggests that the true motive behind the war was to expand the institution of slavery.
-
“[Polk] picked a fight, sending troops to occupy a disputed area of the Texas and Mexico border, and when American troops and the Mexican cavalry clashed, Polk seized the opportunity to declare war on Mexico…” (History, 2017).
- Claim: Accuses Polk of provocatively instigating the conflict, questioning the legitimacy of the war declaration.
