nuclear threat of iran

it's funny how politics work and how much in fact it is affected by economic drives, specially lobbying, tradition, etc.
for instance, the nuclear stand off between iran and US-EU alliance lately coupled with arab nations of persian gulf and middle east. they have been putting so much effort on having iran abandon it's nuclear programme and how iran is a threat to regions stability and the worlds safety. so many sanctions that had made our life, and specially our life as iranians more miserable. these are all where, next door in pakistan, one of the most politically fragile governments, they own nuclear facilities, had clearly stated that they are not in favour of demolishing nuclear weapons by not joining NPT, they own ready to use nuclear heads, they recently recognised the so called "Taliban" group of murderers and gave them authority, who could at anytime launch an attack on the nuclear facilities and steal nuclear warheads! and yet iran is the danger to world and middle east? am i missing something?
