The Assertion is correct but the Reason is incorrect.

The world war ended when the United States dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki in August 1945, causing Japan to surrender. Critics of the US decision to drop the bombs have argued that the US knew that Japan was about to surrender and that it was unnecessary to drop the bombs. They suggest that the US action was intended to stop the Soviet Union from making military and political gains in Asia and elsewhere and to show Moscow that the United States was supreme. US supporters have argued that the dropping of the atomic bombs was necessary to end the war quickly and to stop further loss of American and Allied lives.
