Correct me if I’m wrong, I did not study US history as part of my education, but wasn’t the attack on Pearl Harbour sold to the American public as “unprovoked”?
Yes as is the general historian consensus around the world. There are some that try to make a case that the US also had done bad things, like force open Japan's ports 80 years prior, and then stopped trading oil and airplanes to Japan, as "provoking" a bombing attack. However these are probably the same people that think Russia is being "provoked" into invading other countries...
Essentially though, Japan had imperial ambitions across most of East and Southeast Asia, knew the US wouldn't allow them much more conquest, and miscalculated that attacking first would be the best chess move to negotiate and secure the rest of the Asian territory they wanted.
