Did the CIA give Iran the bomb?

James Risen's new book new book explores some interesting cloak and dagger scenarios. One was called Operation Merlin. The idea involves Iran and includes:

..handing over tainted weapon designs to confound one of America's adversaries - is a trick that has been used many times in past operations, stretching back to the cold war. But in previous cases, such Trojan horse operations involved conventional weapons; none of the former officials had ever heard of the CIA attempting to conduct this kind of high-risk operation with designs for a nuclear bomb.

Seems we used Russian double-agents and successfully gave Iran the plans. The problem:

Iran has spent nearly 20 years trying to develop nuclear weapons, and in the process has created a strong base of sophisticated scientists knowledgeable enough to spot flaws in nuclear blueprints. Tehran also obtained nuclear blueprints from the network of Pakistani scientist Abdul Qadeer Khan, and so already had workable blueprints against which to compare the designs obtained from the CIA. Nuclear experts say that they would thus be able to extract valuable information from the blueprints while ignoring the flaws.

It's like "Spy vs. Spy" in Mad Magazine. Except this is real.
