C, The United States suffered a violent strike that was carried out by foreign empire without any warning.
Explanation:
The quote above, very clearly states, "The United States of America was suddenly and deliberately attacked by naval and air froces of the Empire of Japan...I regret to tell you that very many American lives have been lost." No where in the quote does it talk about the US and its military allies, it doesn't talk about President Roosevelt's frustration, and it doesn't talk about the congress helping to defend the foreign empire. Hope this helps!
