With the state of the world all pointing their weapons at each other, the time has come to disarm. I can see no real value in decimating a city, a military installation or even a presidential residence. This will lead to counter strikes and a state of mistrust. These monoliths are outdated and clumsy, easily being blown out of the air by fighter jets in high altitudes with the explosion destroying more ozone. It would affect you badly to have these weapons even fired from your side.
In fact, with wars coming down to land skirmishes and naval and airborne dog fights, the use of nukes just kills innocent people. This was used in the second world war when armies were entrenched in cities, but this is not done now. Look at ISIS, a city totally occupied by I.S.I.S. will not suffer nukes, and none other will either. The best solution now is to disarm, of course.
But seeing as how they are these big insurance policies, there should be a state where the nukes are controlled by 'social means.' This would mean that groups of representatives from other countries converge on to the area with the launch codes, and agree to launch through 'social means.' This would be where Russia and America have agents on both sides with codes, for example, leading to peace - insurance. Making this a huge collective effort would see like thirty codes per country, making it impossible for anyone to launch.
Or, there could be a treaty where people agree to fire upon those that fire? This would see the vast Northern Hemisphere pointing everything at each other and then there would be like a 'dare you to shoot situation.'
I am out of ideas on this, anyone got any better ones?
