Probably it was fortunate this volume did not include the most recent period of history to Iran's focus upon nuclear weapons and technology. US events have been less clear and determinative for this recent history and its emergence both politically and militarily.
In so being, the Volume does leave a couple of points of interest which may be both relevant and important for all parties to this developing history in the Middle East and elsewhere.
The larger question referred by this Review and Author does raise why would the impact of nuclear weapons, if developed by Iran, be largely different than experienced in the history of nuclear weapons development by others ? Seemingly, unless you conclude only 'madmen' run the Nation of Iran, their own experiences about the uses and misuses of nuclear weapons could be similar to what has already been history and experience for other Nations.
This is only one question and issue. China's developing of the Belt and Road system for trade raises another. Of what need would there be for sea lane transit or overseas bases given land transport ? Further, alignment with Russia and China may have some advantages but they also impose limits which might prove unwanted by Iran. The local impact[regional] seems a most likely consequence for nuclearized Iran than a more direct global impact though this may need further study and defining.
One last thought for now; recent history with Treaty agreement with the US and West has pointed out one of the more fundamental weaknesses of Democracies politically. Iran must certainly have noted this outcome; elections are fundamental to shaping and determining of foreign policy and military decisions for Democracy. Taking place every 4 years or 6 in some instances, 'stability' of more longer term history and events does not argue well for any but shortterm solutions to nuclear problems. Iran can easily see that whims of capricious voting in the US and elsewhere leads to swings in policies and decisions that may not last longer than the times in offices by individuals and particular political interests.
It is something of a suspicion that Iran, beset with their own problems of 'changes' over time may be more interested in something more longer term for their Nation in the Middle East and the World.
Just a few quick thoughts.
