Lets say a country in extreme hostility (e.G. Syria) was given nukes. If that was to happen, the Syrian government would possibly detonate the bomb in a heavily populated area. In my opinion, no one should have nukes, they are weapons of mass destruction and killing is beyond the last resort of how to resolve problems. NO COUNTRY SHOULD HAVE NUKES!
The objective should be total nukes disarm. All resources should be placed on an effort to achieve a total world nuke disarming of all states but as long as states have superpower hegemony ambitions that will not be achieved an can only be possible if a reformed and empowered U N seriously enforces a just world order.
Nuclear arms are so pointless. If you start a nuclear war, you start the end of humanity and the world as we know it. What's the point in that? We all just have these terrifyingly destructive weapons so that we can scare one another? Sounds like a waste of time and money to me.
