Jessica, simple. Just tell them to watch Team America: World Police ;)

But in seriousness, there are a few good books out there that would held them. My friend that I referenced, Peter Zeihan, has a great book on the history of U.S. geopolitics and how we became and Accidental Superpower as well as Kissinger’s book, World Order. Kind of explains the confusing landscape and the weirdness of how everything fell in line for America.
