Timeline (No Nukes)

In our world Nuclear devices have only been used once, Hiroshima and Nagasaki, in 1945 in Japan near the end of WWII. They have the power to wipe out the planet with the accidental press of a button. The thoughts of Nuclear War have inspired Human imagination, Music, Video Games, Books and T.V series. They have caused people to be come paranoid and have consumed billions in state spending as well as a Cold War that spanned 34 years. Strange as it may sound, Nuclear weapons have prevented wars. When India and Pakistan both acquired nuclear weapons wars between them stopped, even if tensions remained high. But what if these weapons simply never produced? What would our world look like?
