By this time, Truman was pessimistic about international arms control and told his advisors "Since we can't obtain international control we must be strongest in atomic weapons." He approved the Harmon report's recommendation for increased weapons production, and approved another increase soon after the start of the Korean War. JCS decided to emphasize "the destruction of known targets affecting the Soviet capability to deliver atomic bombs", with refineries, chemical and power plants, and shipyards as secondary and tertiary targets. The three categories were codenamed BRAVO (blunting), ROMEO (retardation), and DELTA (disruption/destruction) of the Soviet ability to fight, and formed the basis of American nuclear targeting for almost a decade.
