Never has a single country had so many military bases on so many parts of Planet Earth. Consider that a striking fact of 2019, as it was, say, of the 1950s or the post-Cold-War 1990s. How many such bases? As Turse makes clear, no one really knows, possibly not even the Pentagon. And more curious yet, that vast global infrastructure, that "empire of bases" (in Chalmers Johnson's eloquent phrase), is hardly noticed in what, since 9/11, has been known as "the homeland." Few here think much about those global garrisons (although hundreds of thousands of Americans have in recent years been deployed to them); the media that cover every presidential tweet as if it were a missive from the emperor almost never mention them, much less report on them; and no one – Turse and a few scholars aside – seems to have the slightest interest in counting them up, much less considering their cost or even the global role they've been playing all these years. In domestic terms, they are essentially missing in action, which means a vision of how the United States has positioned itself on this planet is missing in action as well.
