There is so much duplicity, dirty-dealing and bad-faith in these deals that nothing should be taken at face value. Everyone's hands are dirty and always behind these pacts are three constants:
1) They are driven by cash
2) The U.S. taxpayers bear the entire financial burden.
3) The cash recipient bears no risk under the agreement.
You will recall the succession of U.S./ North Korean arrangements between 1994 and 2005, in which in return for agreeing to pretend to have ceased its nuclear program, N. Korea received $billions in free hard currency. Over those years the U.S. would dutifully accuse the North Koreans of cheating, N Korea would agree never to cheat again, and $billions more would slide in to Kim Jong il under a revised agreement. Remember the adage: Foreign aid is the process by which the working people of rich countries transfer money to the rich people of poor countries.
So despite what you are seeing in the media and hearing on the Sunday news shows, the only noteworthy issues are the financial ones, many of which are opaque. Iran (unless previously nullified by Israel) will eventually obtain its nuclear weapons, the only question is how much cash it is able to pocket in the interim and to which individuals it is routed. On that note, GATA's Chris Powell put out the following today attached to a Bloomberg article: Iran will be allowed to buy gold but not take it as payment for oil.
And why would you think that might be? Perhaps the west is as much concerned about a thermonuclear explosion of the gold price as the timing of Iran's inevitable announcement of nuclear status. The details are always more important than the headlines.
