There are a few issues with your assumption that, and this is coming from an immigrant of former USSR. 1. It's not the nation-states that posses nuclear weapons that are the most dangerous, it is a possibility of an extremist group getting nuclear weapons. Countries has something to fear, a small criminal/terrorist organization does not. 2. US and Russia has similar nuclear stockpiles, how come economic distribution is different between the two? Nuclear weapons does not make you a "super-power", economy does. Example: Germany has no nuclear weapons yet are an economic power.
