Question

which was not a reason for president mckinley to declare war on spain? spain agrees to cease fire with rebels yellow journalism increases war thirst in americans the de lome letter enrages the u.s public spain refuses to grant cuba independence

Explanation:

To determine which was not a reason for President McKinley to declare war on Spain, we analyze each option. Spain agreeing to cease fire with rebels would reduce conflict, so it would not be a reason to declare war. Yellow Journalism (sensationalist reporting) stoked war - thirst. The De Lome letter (insulting the U.S. President) enraged the public. Spain's refusal to grant Cuba independence was a major grievance.

Answer:

Spain agrees to cease fire with rebels.
