Because Germany attacked U.S. civilian ships.

  1. Germany attacked U.S. civilian ships ✔
  2. Japan bombed Pearl Harbor
  3. To stop the spread of communism

Why: German submarines sank ships carrying Americans, so the U.S. joined the Allied Powers. Pearl Harbor led to World War II, and stopping communism was the reason for Korea and Vietnam.

Huh, didn't know that: The United States entered World War I in April 1917.

The dad joke
Why do seagulls fly over the sea? If they flew over the bay, they'd be bagels.
