Answer:
President Franklin Delano Roosevelt declared
that the day of the Japanese attack on Pearl
Harbor, December 7, 1941, would live in infamy.
The attack launched the United States fully into
the two theaters1
of the world war. Prior to Pearl
Harbor, the United States had been involved in
the European war only by supplying England and
other antifascist countries2
of Europe with
necessary war materials.
The attack on Pearl Harbor also launched a rash
of fear about national security, especially on the
West Coast. In February 1942, just two months
after Pearl Harbor, President Roosevelt as
commander-in-chief, issued Executive Order
9066, which had the effect of relocating all
persons of Japanese ancestry, both citizens and
aliens, inland, outside of the Pacific military zone.
The objectives of the order were to prevent
espionage3
and to protect persons of Japanese
descent from harm at the hands of Americans who had strong anti-Japanese attitudes.
