Trivia: The U.S. entered Vietnam partially due to a theory named for what toy?
Rubik’s Cube
Slinky
Domino
Hula Hoop
The correct answer is Domino
So why is this answer correct? : During the Cold War, the so-called “Domino Theory” suggested that one nation becoming Communist would quickly lead to Communist takeovers in neighboring nations. This idea led to the United States’ entry into the Vietnam War, in an attempt to block the North Vietnamese from aligning Vietnam with the USSR.
