Read the quote from Albert Einstein."I made one great mistake in my life, when I signed the letter to President Roosevelt recommending that atomic bombs be made; but there was some justification—the danger that the Germans would make them.”

The best choice is that he understood the destruction the bomb could cause in the world.
