Its very easy to say we should go back to swords and arrows, but not very practical. The technology is out there and it is impossible to go backwards. Even if all the world's governments decided to ban all weapons, some people will fashion boards with nails on them and rule the world.
We cannot deny the worst about our own nature, and the fact that bad men with guns will always be a part of the world. To take the high road with those who do not care about your principles is the same as allowing those people to rule you.
While the world may have been a scary place at times during the Cold War, no one died by the hands of the nuclear weapons the sole reason that their enemies had them too.
