The main goal of the bombings at Pearl Harbor was to frighten the United States from entering the war as they had stationed much of their Pacific fleet at Pearl Harbor. This was perceived as a threat to the imperial ambitions of Japan.
The answer is: The US still had to defeat Japan
VE day refers to the day when the Nazi surrendered to the alliance during the world war ii, which occurs on May 3rd 1945.
At that time, our enemy during world war Ii was not Germany alone. Germany formed a strong coalition with Italy and Japan in a group called the Axis-power.
Italy has surrendered 2 years before Germany. Which means that after the VE day, United states still had to defeat Japan who had a very strong foothold in Asian territory.
They were better because there was more space (it wasn't already taken by the country industrialising itself), and there was no competition from the country itself, it's like us walking into a tribe nowadays, our technology is <em>extremely</em> superior so we could waltz in if we wanted to, in so if someone expanded from a modern society into a non industrialised country it would be effortless.
