Following WW1, which was considered by most Americans as a futile war of little importance to the US, the US entered a consensus (majority agreement) that they should adopt a policy of "isolation" towards Europe, which was increasingly unstable. The US public did not want to be drawn into another European war. Although, the US mantained strong economic links, such as the various economic bailouts and loans they gave to Germany's Weimer Republic and exported greatly to Europe.

The second, which hit Nagasaki on 9 August, killed at least 50,000 people – according to some estimates, as many as 74,000 died.<span>It was certainly a reasonable view for the USA to take, since they had suffered the loss of more than 418,000 lives, both military and civilian. To the top rank of the US military the 135,000 death toll was worth it to prevent the “many thousands of American troops [that] would be killed in invading Japan” – a view attributed to the president himself.</span><span>the US wasn’t justified. Even secretary of war Henry Lewis Stimson was not sure the bombs were needed to reduce the need of an invasion: “Japan had no allies; its navy was almost destroyed; its islands were under a naval blockade; and its cities were undergoing concentrated air attacks.”</span><span>The atom bombs achieved their desired effects by </span>causing maximum devastation<span>. Just six days after the Nagasaki bombing, the Emperor’s Gyokuon-hōsō speech was broadcast to the nation, detailing the Japanese surrender. The devastation caused by the bombs sped up the Japanese surrender, which was the best solution for all parties.</span>
