What were the major results of the japanese attack on pearl harbor?

The two major results of pearl harbor were 1. the united states entering ww2, ultimately ending with the bombing of hiroshima and nagasaki and 2. the fear of japanese - american citizens that led to the terrible so called "relocation camps" for the rest of the war

This act gave the federal government the power to relocate any native in the east to territory west of the mississippi river.
