Its getting to a very interesting stage, the sanctions are extremely severe and would have an immediate impact. I can only assume that the sanctions are made that way to provoke a major confrontation.
Obama is pinned down domestically and a major confrontation would divert a lot of pressure of him economically. Congress have basically given Obama permission to go to war. So if its going to be a fizzer then it better fizz soon.
The sanctions virtually wipe out oil revenue to Iran . Either Iran will back down or they will do something spectacular.
Gold (physical) has to be a good thing at these prices IMO
