But will that happen? I doubt it. A country like America likes authoritarian regimes that like to listen to America. So Iranian things in the best interest of America would be the same theocracy but docile to America at least in the near future (or worse a full fledged military dictatorship which they anyway installed once).
However I just hope/dream (and it's too much of a hope) for the sake of Iranian people - it ends up getting a democracy after all (maybe).
However there is one thing clear - there is no rule based foreign relations, business, diplomacy anymore in this post truth world of ours. It's plain simple - you look after your own hind lest you find someone is at the door wanting to take it; might be an ally just as well.
A side note: I can't thank four of my country's ex PMs [0] enough that they ensured we had nukes inspite of stringent sanctions from other nations which ironically, among them, almost all already had nukes :D
The point is - we wish there were no nukes in our heating beautiful world; but tough luck, so you better get your own and get it soon.
[0] esp. Indira Ghandhi; also, probably the only head of sate that actually succeeded in "selling freedom" thing. Something America specialises in and uses as a premise to routinely reduce various parts of the world to rubble. A positive outcome of such endeavours - its defence industry getting push from it and of course it goes about trying to re-build it, giving push to other of its industries, half or quarter way and then finds other sundry places to subject to this routine.
