Robert Oppenheimer changed the world when he helped develope the first A-bombs. The A-bombs made Japan surrender in WWII so that US troops did not have to invade the mainland. This saved the lives of millions of US troops, the casulty rate was estimated to have been 75% if it had occured. Many people in the US would not be alive today if Robert Oppenheimer had not developed the A-bomb.
