So lets debate them ... I propose ideas, and they are not all right, wrong, or indifferent. Everything really needs to be taken as a package.
To answer your questions ... The Iranians I know do not want the Mullah's to rule Iran. They would much prefer something closer to what we have in the U.S.
In terms of building a bomb ... They say probably not, But they also say no one knows. There is no verifiable evidence, and they are aware of that.
In terms of Sanctions being removed ... IMHO - The point is that we will do it if they are willing to trade their goods in dollars ... It will become an economic necessity because we need to keep the petro-dollar going. It has nothing to do with "Being So Grateful". It will be initiated by the U.S.
