A) using an earlier case as a guide.
The German government issued The Sussex Pledge that basically told the U.S. that they were going to change their policies on navel war.
The country that the United States sent soldiers to in order to prevent communism was <u>Korea</u>.

They therefore sent soldiers to South Korea which escalated the Korean War but protected South Korea.
