Give it up, Iran is destined to be a Nuclear power, besides the nuclear cat is out of the bag.
The most important factor is manpower, Iran already has the scientists and engineers, and they have already gathered bought/stolen the technology and reverse engineered it.
This takes time, Pakistan took 12 years to do it from 72-87,
Iran will be starting from a more advanced position than pakistan in 72.
Nuclear technology is now readily available, Most of Iraqs nuclear scienits were Egyptians on loan, so you would expect that egypt could start a weapons program quickly, if they werent broke.
Syria has the manpower too but it too is broke.
If either of them finds a new oil field of something then you will have another Ãran.
