It’s always interesting to talk to people during a difficult economic time in the United States. At some point during most conversations, someone will make a reference to how the US might do better on its own, rather than worrying about the rest of the world’s issues. While these statements are usually presented as jokes, they speak to a very interesting and significant aspect of US history—isolationism. In case you’re worried you don’t know nearly enough about something this historically important, never fear! I learned a great deal about this topic in one of my favorite undergraduate classes, Domestic Politics and US Foreign Policy, and now will pass it along to you.
