The correct answer to this open question is the following.
This would be the answer to Spain's request.
To her Royalty Majestic Government,
It is with the utmost respect that I answer your previews letter regarding the shameful incident of the sinking of the USS Main on the coast of the Island of Cuba, on February 15, 1898.
The United States has deeply researched the case and the version is totally different from the information you are sharing in your letter.
As you would understand, the United States is in a state of shock after that terrible incident. We consider this as ad direct aggression to the US Navy and a flagrant act of war against the United States of America.
Regretfully, the United States government has to make some difficult decisions concerning this incident and at this very moment, I am about to address Congress to make a final decision on this case.
As soon as we have concluded on a final decision we will be accordingly informed.
