I want to know the answer to the following question:
How many US citizens were killed in the attack on Pearl Harbor by Japan?
All the background I'm provided with is that "In the early hours of 7 December (Hawaiian time), Japan launched a major surprise carrier-based air strike on Pearl Harbor without explicit warning, which crippled the U.S. Pacific Fleet, leaving eight American battleships out of action, 188 American aircraft destroyed, and 2,403 American citizens dead.". Is that enough to answer the question?
