It possibly did reduce the chances of future global wars. Unfortunately it probably increased the amount of local ones.
Many would disagree and have other interpretations of the effect or lack of it.
Radiation poisoning and genetic mutation was an unexpected result of the Atom bomb, but the threat of future wars destroying the human race is the enduring legacy of the bomb
Only WW2.

One thing is that since the age of atomic weapons there has not been any more world wars.
The development of the atomic bomb was not only the most ambitious scientific enterprie in history, it was also the best-kept secret of the war.
World War 2 :)
Scientists view the atomic bomb as a tool to prevent wars. However, when they realized the destructive power of the weapon they were horrified that it had been discovered.
To get a car bomb on Mafia Wars you have to buy it using reward points.
The U.S. originally built the atomic bomb to end WW2 because it was the only alternative to invading Japan, which would have cost many, many more lives and been worse for all involved. Now atomic bombs are used for a balance of power - "If you nuke us we'll nuke you back" is enough to stop a few wars.
Future Wars happened in 1989.
The goal was to prevent future wars
For most military planners the atomic bomb (and later the hydrogen bomb) was just a more powerful version of existing bombs. It therefore had practically no impact on their ideas of how wars would be fought. Some however decided that only bombers would be needed to destroy any adversary, the rest of the military could be eliminated to save money. However with the beginning of the Korean war it began to be realized that some wars might be "too small" to make the atomic bomb appropriate to use.
