This is a long book, but good. And literally ANY part of it can be valuable reading. Samantha Power is currently the Administrator of the U.S. Agency for International Development (U.S. AID), and she is a former U.S. ambassador to the United Nations, a foreign policy advisor to Barack Obama, and a journalist who covered (and wrote a book on) genocide in Eastern Europe and Africa. This book is essentially her memoir, but it's also a great exploration of how someone's views changed throughout their experiences and how she worked to change and improve institutions (as a diplomat) that she once criticized (as a journalist.) 

If you don't want to read an entire book, but maybe just a few chapters, this is an excellent choice! There are ten chapters that all start with a map of a specific country and its borders. Marshall analyzes how these maps influence the ways that countries behave (like why Russia is so aggressive with its neighbors, why China makes outrageous claims about its borders, and why the U.S. was able to dominate so much of the 20th century.) Rather than focusing people and ideas, which can change, Marshall argues that Geography (which is unchanging) is a dominant factor in explaining why countries act the way they act.

Those of you with an interest in Economics might enjoy this one! Economic Development is one of the major themes of the Global Politics course, alongside Globalization, which explains how and why the world has become increasingly interconnected and interdependent over the last fifty years (or four-hundred years, depending on who you ask.) Dr. Rivoli personally follows the path that a T-Shirt takes from the cotton fields of Western China all the way to a storefront in the United States. An intriguing mix of history, economics, culture, and sociology -- this is a terrific read.

News and commentary magazine updated on a regular basis. These articles tend to be written for an educated audience, so they are not easy, but the writers are GREAT and there is a wide variety of articles. Articles on international events are your best bet here. 

You will run into the Times' "paywall" after reading a few articles. Open the page again in "Incognito Mode" and you should be able to continue reading. The New York Times is widely considered one of the best newspapers in the world, and their world news section is second to none. 

Also writes on international affairs, but most articles have a pretty obvious interest in economic ideas, factors, and decisions.

It's from England, but that's ok. We'll forgive them. (This is a rather good news source, often with shorter articles that are more direct about what is going on.)

I don't think the name leaves much to the imagination -- you should know what to expect here :)

Map-based articles, usually focused on things linked to the U.S., but occationally covering broader topics.
