Final answer:
Secretary of State Buchanan presented three arguments for a possible war with Mexico: monetary claim, border dispute, and national security.
Step-by-step explanation:
Arguments by Secretary of State Buchanan for a possible war with Mexico:
- Monetary Claim: One argument was that U.S. citizens had monetary claims against the Mexican government that remained unsettled, such as unpaid loans and damages for seized property.
- Border Dispute: Another argument was the ongoing boundary dispute between the U.S. and Mexico over Texas. The U.S. claimed the border was the Rio Grande, while Mexico argued it was the Nueces River.
- National Security: A third argument was centered around national security concerns. Supporters of the war believed that a military campaign could lead to the acquisition of Mexican territory, providing a buffer zone and enhancing U.S. security.
These arguments, among others, played a role in justifying the possible war with Mexico.
