How did the De Lome letter affect U.S.-Spanish relations?

The De Lome letter, written by the Spanish minister to the United States, criticized President McKinley, referring to him as weak and criticized U.S. policies regarding Cuba. When this letter was leaked to the press in early 1898, it caused a significant public outcry in the United States. Many Americans viewed the letter as an insult to their nation and its leadership, which exacerbated existing tensions between the U.S. and Spain, particularly in the context of the Cuban War for Independence.

The controversy surrounding the letter stoked public sentiment against Spain, contributing to a growing desire for intervention in Cuba and ultimately leading to the Spanish-American War. Thus, the De Lome letter is seen as a catalyst that intensified the existing animosities, making B the correct choice as it highlights how the letter escalated tensions and contributed to a shift in public and governmental opinion towards a more aggressive stance against Spain.
