how did many americans respond to the declaration of war with spain?\nmost believed the army was not…

Brief Explanations:

When the U.S. declared war on Spain (Spanish - American War), there was significant patriotic fervor. Many Americans saw it as a just cause (e.g., helping Cubans gain independence from Spanish rule). The idea of military service was seen as a noble and patriotic act. There was no large - scale fear that the army was unprepared in a way that would stop men from volunteering. Florida was not a major concern in terms of Spanish conquest at that time. And there was no widespread large - scale anti - war demonstration of "tens of thousands" against the war declaration.

Answer:

Many men volunteered for military service.
