In an ideal future, firearms would be banned worldwide.

A body like interpol would investigate the entire world, to surveil if anybody is trying to make firearms.

People would make bows and spears, but it would be more difficult to conduct war.

It would not make war and violence impossible, but it would certainly be a better world.

EDIT: lots of pedants:

obviously there would be an joint army answering to an international body whose only mission is to seize and destroy weapons.

firearms includes bombs and other lethal ammunition, of course. Not knives.
