Revealing mistake: When the Marines shoot the Japanese pilot, you can see the wire used to set off the blood bags coming out of his pants leg as he falls. (01:11:30)

Revealing mistake: When the Zeros destroy the yacht, mooring lines can be seen holding the boat in place as it explodes. Obviously, it isn't actually at sea, but is very near shore. (00:45:35)
Answer: FDR's Four Freedoms speech (which was his eighth State of the Union address) was originally given on January 6, 1941, some months before Japan attacked Pearl Harbor on December 7, 1941. The filmmakers appear to have deliberately compressed the two historical events to emphasize the dramatic change in the world. FDR gave the speech to gain public support for the U.S. aiding Britain and the other allied forces, even though it was not yet involved in the war.
