Read this passage from a speech by Ronald Reagan in 1983. I urge you to beware the temptation of . . . [labeling] both sides equally at fault, to ignore the facts of history and the aggressive impulses of an evil empire, to simply call the arms race a giant misunderstanding.

Which best describes the meaning of Reagan’s words?

Both sides in the Cold War are evenly to blame.
The Cold War has been based on a giant misunderstanding.
The Soviet Union is a cruel nation that started the Cold War.
The lesson of history is that the Cold War is separate from the arms race.
