American military bases encircle the globe with nearly 1,000 locations in foreign lands. These bases are usually taken for granted or overlooked entirely. But in an eye-opening account, Base Nation shows that the worldwide network of bases brings with it a panoply of ills - and actually makes the nation less safe in the long run.

As David Vine demonstrates, the overseas bases raise geopolitical tensions and provoke widespread antipathy toward the United States. They also undermine American democratic ideals, pushing the US into partnerships with dictators and perpetuating a system of second-class citizenship. They breed sexual violence, destroy the environment, and damage local economies. And their financial cost is staggering: though the Pentagon underplays the numbers, Vine's accounting proves that the bill approaches $100 billion per year.

With the US withdrawing from Afghanistan and ending 13 years of war, there is no better time to reexamine the tenets of our military strategy. Base Nation is an essential contribution to that debate.
