One I was reading on a collected DVD, an Uncle Sam story from the Lou Fine illustrated run in NATIONAL COMICS 18, cover-dated December 1941. A 9-page story that portrays an attack by "oriental" forces on U.S. bases in Guam and Pearl Harbor, done so the Germans could simultaneously wage an air-bombing and naval attack on the U.S. East coast.

You can read the complete story here:

A story portraying a Japanese attack on Pearl Harbor, cover-dated the same month as an actual attack on Pearl Harbor by the Japanese!
