Which former documents were used to justify fighting the Spanish?

The justification for fighting the Spanish, particularly during the Spanish-American War, was rooted in several key documents. The De Lôme Letter, which criticized President McKinley, fueled public outrage, while the explosion of the USS Maine in Havana Harbor was depicted as a direct attack on the U.S. These events, combined with the publication of sensationalist newspaper articles (yellow journalism), helped galvanize public support for military action against Spain. Additionally, the Teller Amendment, asserting that the U.S. would not annex Cuba, framed the conflict as a liberation effort.
