My op-ed in The Washington Examiner explores the many different versions of the country that might have emerged over the past 250 years if Americans had pursued different visions for their country, or the tides of history had taken other paths.
My op-ed in RealClearDefense makes the case that the Battle of Trois-Rivières 250 years ago is worth remembering because it preserved the possibility of an independent Canada. While July 4 is America's 250th anniversary, June is, in a way, Canada's own 250th birthday.
I argue in The Hill that Donald Trump is the most ambitious annexationist president in the modern era, but he's unlikely to achieve any of his territorial goals.
I tell the fascinating story of Rio Rico in The New Republic. A town that was part of Mexico in every practical sense turned out to be built on American soil. Were children born there U.S. citizens?
I write in Law & Liberty about America's evolving history of expansionism, and why annexation gave way to other forms of international influence and control.
My piece in The Hill examines the long history of U.S. attempts to annex Cuba, and how they inform today's debates over the island.
I suggest in RealClearDefense that instead of trying to annex Greenland, the U.S. should revive the post-World War II model of free association.
I argue in The Hill that Donald Trump's questions about why Denmark has a right to Greenland display historical amnesia. The piece was republished in The Washington Post.
American Heritage published an excerpt from America, but Bigger: The story of America's first attempt to acquire Greenland after the Civil War.
One of Japan's largest newspapers, Sankei Shimbun, quoted me in an article about America's 250th birthday.
