Is it real or just smoke?

At a press conference this morning US Secretary of State, John Kerry announced an agreement with Iran at Geneva. Under this Iran has agreed to halt all uranium enrichment beyond 5%, give up its stockpile of uranium enriched to 20% and stop further work on the nuclear reactor at Arak which would have given it an alternative fuel, plutonium for nuclear weapons. Iran also agreed to " intrusive monitoring " by the IAEA of its nuclear facilities and may repair existing centrifuges but not install new ones. Iran will be allowed to sell 1 million barrels of oil per day but will receive only $4.2 billion every month from sales, the rest of $15 billion will go into international restricted accounts. The language was surprisingly harsh. " If Iran fails to meet its commitments we will revoke the relief." " Sanctions affecting crude oil sales will continue to impose pressure on Iran's government." The agreement is for 6 months and it is on Iran to prove that it is complying with its promises, if not sanctions will be reimposed. " The concessions Iran has committed to make as part of this first step will also provide us with increased transparency and intrusive monitoring of its nuclear program." So, is this the most humiliating defeat for Iran since Darius III was defeated by Alexander in the Battle of Issus in 333 BC. Iranian Foreign Minister, Mohammad Javad Zarif appeared surprisingly cheerful given what Kerry had just told everyone. It maybe because Iran got the most important concession of all. Although there is no specific mention of it Iran has achieved what it has been demanding all along and that is the right to enrich uranium for peaceful purposes, even if it is only up to 5%. Having achieved what it set out to do Iran can afford to cooperate with every demand that the western countries make and gradually get the sanctions lifted, knowing that once they are completely gone it will be very difficult to impose them again. Iran has the infrastructure and the knowledge and can afford to wait for a year or two to get nuclear weapons, which is what it wants. So Kerry's posturings were to reassure Israel and Saudi Arabia, which has threatened to obtain nuclear weapons from Pakistan, and Republicans back home. Israel has already called the agreement an early Christmas present for Iran. So, is all this merely smoke or will it really stop Iran?
