The Royal Navy anticipated a surprise blow in principle

British officers could imagine a Japanese surprise strike without possessing intelligence that fixed Pearl Harbor as the target.

Question

How foreseeable was the attack on Pearl Harbor to the Royal Navy?

Short answer

The form of a sudden strike was foreseeable, but Britain did not have specific intelligence proving Pearl Harbor was the chosen target.

Notes

The answer distinguishes strategic imagination from actionable warning. Royal Navy officers considered attacks on both Pearl Harbor and Singapore because a hard opening blow fit their own operational instincts. That did not mean Britain knew where or when Japan would strike. Identifying a plausible enemy method did not resolve its target, timing, or force allocation.
