Reading outside the classroom, however, I began to fit the pieces of history into a larger mosaic. What at first had seemed like a purely passive foreign policy in the decade leading up to the First World War now appeared as a succession of violent interventions: the seizure of the Panama Canal zone from Colombia, a naval bombardment of the Mexican coast, the dispatch of the Marines to almost every country in Central America, occupying armies sent to Haiti and the Dominican Republic. As the much-decorated General Smedley Butler, who participated in many of those interventions, wrote later: "I was an errand boy for Wall Street."
At the very time I was learning this history-the years after World War II-the United States was becoming not just another imperial power, but the world's leading superpower. Determined to maintain and expand its monopoly on nuclear weapons, it was taking over remote islands in the Pacific, forcing the inhabitants to leave, and turning the islands into deadly playgrounds for more atomic tests.
In his memoir, No Place to Hide, Dr. David Bradley, who monitored radiation in those tests, described what was left behind as the testing teams went home: "[R]adioactivity, contamination, the wrecked island of Bikini and its sad-eyed patient exiles." The tests in the Pacific were followed, over the years, by more tests in the deserts of Utah and Nevada, more than a thousand tests in all.
When the war in Korea began in 1950, I was still studying history as a graduate student at Columbia University. Nothing in my classes prepared me to understand American policy in Asia. But I was reading I. F. Stone's Weekly. Stone was among the very few journalists who questioned the official justification for sending an army to Korea. It seemed clear to me then that it was not the invasion of South Korea by the North that prompted U.S. intervention, but the desire of the United States to have a firm foothold on the continent of Asia, especially now that the Communists were in power in China.
Years later, as the covert intervention in Vietnam grew into a massive and brutal military operation, the imperial designs of the United States became yet clearer to me. In 1967, I wrote a little book called Vietnam: The Logic of Withdrawal. By that time I was heavily involved in the movement against the war.
