If you have a serious interest in American Foreign Policy, particularly its military component, you need to read the article which I begin and link to below, from the distinguished foreign policy journal of the "Realist" school, In The National Interest
In the last five months of World War II, American bombing raids claimed the lives of more than 900,000 Japanese civilians—not counting the casualties from the atomic strikes against Hiroshima and Nagasaki. This is more than twice the total number of combat deaths that the United States has suffered in all its foreign wars combined.
On one night, that of March 9-10, 1945, 234 Superfortresses dropped 1,167 tons of incendiary bombs over downtown Tokyo; 83,793 Japanese bodies were found in the charred remains—a number greater than the 80,942 combat fatalities that the United States sustained in the Korean and Vietnam Wars combined.
Since the Second World War, the United States has continued to employ devastating force against both civilian and military targets. Out of a pre-war population of 9.49 million, an estimated 1 million North Korean civilians are believed to have died as a result of U.S. actions during the 1950-53 conflict. During the same war, 33,870 American soldiers died in combat, meaning that U.S. forces killed approximately thirty North Korean civilians for every American soldier who died in action. The United States dropped almost three times as much explosive tonnage in the Vietnam War as was used in the Second World War, and something on the order of 365,000 Vietnamese civilians are believed to have been killed during the period of American involvement.
While this is a very long article, a "white paper" is perhaps more appropriate, your time will be well spent.
