More than 58,000 American troops and personnel died in the humid jungles and muddy rivers of Vietnam during the 20-year conflict. But why? What were they fighting for? And how could the world's most powerful military be defeated by a small, poverty-stricken country?

In The Vietnam War, kids ages 12 to 15 explore the global conditions and history that gave rise to the war, the reasons why the United States became increasingly embroiled in the conflict, and the varied causes of its shocking defeat. As readers learn about how the fear of the spread of communism spurred the United States to enter a war that was erupting on the other side of the world, they find themselves immersed in the mood and mindset of the Vietnam Era.

The Vietnam War is one book in a set of four that explore great events of the twentieth century. Other titles in this set include Globalization: Why We Care About Faraway Events; World War II: From the Rise of the Nazi Party to the Dropping of the Atomic Bomb; and The Space Race: How the Cold War Put Humans on the Moon.
