Showing results for "American Dirt" in History

J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

At the end of the American Revolution, Britain and the United States imagined a future for each of their nations that stretched across a continent. They signed treaties with one another dividing lands neither country could map, much less control. A century and a half later, Canada and the United States had largely fulfilled those earlier ambitions. Both countries had built nations that stretched from the Atlantic to the Pacific and had made an expansive international border that restricted movement.
