PLEASE HELP IT'S LATE I WILL GIVE BRAINLIEST!
Between the late 1800s and the post-World War I era, the United States witnessed a transformation in foreign policy. Write a detailed summary that covers American foreign policy before 1930. You will need to give some succinct but essential background, beginning with the changes that took place in foreign policy during the late nineteenth and early twentieth centuries, and the reasons for those changes.

First, list at least three topics you will cover. Then write one paragraph about each one. The information should relate only to foreign policy between 1867 and 1920.
