Reconsidering Truman's claim of ‘half a million American lives’ saved by the atomic bomb: The construction and deconstruction of a myth

This essay, based on substantial archival research, critically examines President Harry S. Truman's often‐cited post‐World War II claim that he had received pre‐Hiroshima counsel in 1945 that the invasion(s) of Japan could cost ‘half a million American lives’. This essay concludes that there is no 1945 archival evidence supporting Truman's postwar contention, and that there is substantial evidence undercutting his claim. Moreover, in view of the total size of American forces scheduled for 1945–46 operations against Japan, any claim of 500,000 American dead seems implausible. This essay also critically examines how Truman's postwar memoir claim of ‘half a million American lives’ was constructed, and this essay discusses the many and rather varied casualty/fatality numbers that Truman presented during his White House and post‐presidential years. Such an analysis also focuses on the numbers he privately provided in the construction of his memoirs by ‘ghost’ writers. Reaching beyond the specific question of Truman's claims, this essay also discusses the dangers of analysts relying heavily upon post‐event memoir and interview sources, and this essay emphasises the need generally to instead privilege contemporaenous archival materials. Otherwise, analysts risk letting policymakers, often in self‐serving recollections, shape the history of crucial events.

This article examines Edward Lansdale's return to South Vietnam during the Johnson administration. Lansdale offered a persuasive critique of the mistakes the American policy in Vietnam, but his potential influence was severely limited by a combination of bureaucratic infighting in Saigon and a general indifference to the political aspects of the conflict in Washington. While Lansdale was unable to signiflcantly influence the policies of the Johnson administration, his experience in Saigon during 1965–68 offers historians a unique perspective on many facets of American and South Vietnamese policymaking during a crucial period of the Vietnam War.     

Rebellion,Repression and Welfare

I develop a dynamic model of social conflict whereby manifest grievances of the poor generate the incentive of taking over political power violently. Rebellion can be an equilibrium outcome depending on the level of preexisting inequality between the poor and the ruling elite, the relative military capabilities of the two groups and the destructiveness of conflict. Once a technology of repression is introduced, widespread fear reduces the parameter space for which rebellion is an equilibrium outcome. However, I show that repression-driven peace comes at a cost as it produces a welfare loss to society.     

Strategic dynamic sourcing from competing suppliers with transferable capacity investment

We study the supplier relationship choice for a buyer that invests in transferable capacity operated by a supplier. With a long‐term relationship, the buyer commits to source from a supplier over a long period of time. With a short‐term relationship, the buyer leaves open the option of switching to a new supplier in the future. The buyer has incomplete information about a supplies efficiency, and thus uses auctions to select suppliers and determine the contracts. In addition, the buyer faces uncertain demand for the product. A long‐term relationship may be beneficial for the buyer because it motivates more aggressive bidding at the beginning, resulting a lower initial price. A short‐term relationship may be advantageous because it allows switching, with capacity transfer at some cost, to a more efficient supplier in the future. We find that there exists a critical level of the switching cost above which a long‐term relationship is better for the buyer than a short‐term relationship. In addition, this critical switching cost decreases with demand uncertainty, implying a long‐term relationship is more favorable for a buyer facing volatile demand. Finally, we find that in a long‐term relationship, capacity can be either higher or lower than in a short‐term relationship. © 2009 Wiley Periodicals, Inc. Naval Research Logistics 2009     

Information security: Designing a stochastic‐network for throughput and reliability

Todas information and communication network requires a design that is secure to tampering. Traditional performance measures of reliability and throughput must be supplemented with measures of security. Recognition of an adversary who can inflict damage leads toward a game‐theoretic model. Through such a formulation, guidelines for network designs and improvements are derived. We opt for a design that is most robust to withstand both natural degradation and adversarial attacks. Extensive computational experience with such a model suggests that a Nash‐equilibrium design exists that can withstand the worst possible damage. Most important, the equilibrium is value‐free in that it is stable irrespective of the unit costs associated with reliability vs. capacity improvement and how one wishes to trade between throughput and reliability. This finding helps to pinpoint the most critical components in network design. From a policy standpoint, the model also allows the monetary value of information‐security to be imputed. © 2009 Wiley Periodicals, Inc. Naval Research Logistics, 2009
