Final answer:
The newspapers were not justified in concluding that Spain was responsible for the sinking of the Maine. Recent examinations of the evidence suggest that the explosion was likely an accident.
Step-by-step explanation:
Based on historical evidence, the newspapers were not justified in concluding that Spain was responsible for the sinking of the Maine. Recent examinations of the evidence have led many historians to conclude that the explosion was likely an accident due to the storage of gunpowder close to the boilers on the ship.
In 1898, without ready evidence, the newspapers called for a war with Spain, which sold papers and rallied the American public behind the cry. The sensationalist newspaper headlines and the lack of concrete proof indicate that the newspapers reached a hasty and biased conclusion without concrete evidence linking Spain to the destruction of Maine.
