Iran has boldly been pursuing several big science projects that have dual use. The space program for the Islamic Republic of Iran is unlikely to foster a business of launching commercial satellites or out-of-this-world travel packages for more than space monkeys, unlike Richard Branson's Virgin Galactic or Space X.
The same technology used for launching spacecraft can be applied to military applications like ICBMs.
The other Iranian project is nuclear power. Why an oil rich nation needs to have nuclear power for peaceful endeavors is dubious. But the Iranians have been refining their "peaceful" products from centrifuges to create bomb grade nuclear fuel. Moreover, these nuclear sites have been scattered throughout the country and many have been buried.
As of January 20th, 2014, an "interim" accord between the six major powers and Iran takes effect. The pact, facilitated by U.S. Undersecretary of State Wendy Sherman, lifts hard fought international sanctions and access to $4.2 billion in frozen assets which have been crippling Tehran regime in exchange for a six month promise to dilute half of its 20% enriched uranium to 5% enriched uranium levels.
The Iranians feel free to continue their "research" and need not dismantle facilities. The Iranians believe that this interim agreement legitimizes its nuclear program, while the west disagrees. Moreover, the Iranian chief negotiator Abbas Aranqui, indicates that there are "non-papers" or secret side agreements which validate Iran's right to continue nuclear research along with a joint commission to oversee the deal.
Despite assertions that these sanctions can quickly be reapplied if Tehran is proven to be pursuing a non-peaceful nuclear program, this talk is worth the paper on which it is written. It is highly unlikely that the Russian Federation and the Peoples Republic of China will be open to reapply these hard fought for international sanctions, especially if the free flow of Iranian oil and a fly in the West's ointment helps their positions.
Iran need not build an extensive atomic arsenal to try to annihilate America, which revolutionary Iranian government still considers "the Great Satan". A few placed nuclear bombs on ICBMs set to explode in the atmosphere could effective bomb America into the stone-age via an EMP, an electromagnet pulse.
So much for Farsi-cal (sic) scientific projects. It's a pity that the responses in most of the West to these Iranian provocations seems like a sick joke.
