Classic Russian Strategy

Unless you eat up Pentagon propaganda, the clear truth is that the Iranian Government, -theocratic and despotic as it may be- is not at all interested in building, much less using a Nuclear bomb. This is not to say there aren't some extremist Iranians who would be, but they are not backed by the government. This may seem suprising given that Israel possesses an undisclosed number (likely in the low hundreds) of nukes, but Nuclear weapons (as well as Biological and Chemical) are theologically unacceptable in Iran, The Ayatollahs won't have any of it.

The point I was trying to make was not that Turkey would be irresponsible with nuclear weapons, (actually in the past they've proven quite responsible with nuclear weapons they had acquired during the Cold War through NATO's Nuclear Sharing program.) but that Iran and Turkey should be put on an equal footing when it comes to their rights (under the Nuclear Non-Proliferation Treaty, of which both nations are signatories) to a civilian Nuclear Energy Program, which mind you is technologically dissimilar from and not compatible with a Nuclear Weapons Program.
