It is very odd that the attack is often taught as something just out of the blue - e.g. there was the Japan War Scare of 1906-1907 https://www.globalsecurity.org/military/ops/japan1906.htm and Japanese citizens in the US were bascially treated like 2nd class citizens stoking up a lot of resentment (not that I'm defending the attack or the Japanese military/fascist leadership!)
