Who said it?

I think we'd be better off if we, in fact, backed off those sanctions (on Iran), didn't try to impose secondary boycotts on companies . . . trying to do business over there . . . and instead started to rebuild those relationships.

Also:

We're kept out of [Iran] primarily by our own government, which has made a decision that U.S. firms should not be allowed to invest significantly in Iran. I think that's a mistake.
