I don't think Vasco ever implied that the Iran were copying the USA, in fact the reverse is probably more accurate.
It looked to me that he was pointing out the fallacy in carrying out that kind of policy (bad news/press travels faster than good).
US foreign policy is probably best described as a road that was meant to be paved with best intentions, but it didn't quite pan out that way (which is pretty much par for the course when it comes to empire building).
We'll let you off though, you're new at this kind of thing.
