In fact, the real issue was not nuclear weapons, which Iran does not now possess, but Iran's potential geopolitical power.

Iran, a nation of 80.8 million, has been bottled up like the proverbial genii by US-led sanctions ever since the 1979 Islamic Revolution deposed Shah Pahlavi's corrupt royalist regime. The Shah had been groomed to be the chief US enforcer in the Gulf.

More than a dozen American efforts to overthrow the Islamic government in Tehran have failed. Washington resorted to sabotage and economic warfare, sought to throttle Iran's primary exports, oil and gas,  to derail its banking system, and prevent imports of everything from machinery to vitamins. 

The US and Israel have used the extremist group People's Mujahidin to murder Iranian officials and scientists.
