Final answer:
The Spanish government was the least eager to go to war against Spain, fearing the loss of their empire and further uprisings influenced by a Cuban bid for independence.
Step-by-step explanation:
Of all the parties involved, the Spanish government was least eager to go to war against Spain. The Spanish reluctance was primarily due to their fear of losing more control over their empire after a series of revolutions had already weakened their grasp on Latin America.
Furthermore, they were concerned about the repercussions Cuban independence might have in triggering more uprisings and increasing the skepticism among the Spanish populace towards the monarchy. On the other hand, the American government, the American people, and the Cuban rebels had their reasons to push against Spanish control, but none were as hesitant as the Spanish government itself.
