Weapons are the reason there is peace in the world after WW2. Countries with no lethal weapons like Syria are facing war as of now while North korea doesn't.
Firstly, this peace has no guarantees, secondly, the potential destruction is only increasing with the time. Do you think that every country will have nukes in the future? Do you think it is the smartest of all possibilities?
Nuclear weapons could make irreversible changes on the Earth. It is much dangerous than any war.
