It's not possible to know what would have happened if Mossadegh was left alone by the US. It seems to me that the article hinted at conservative elements taking over regardless, and there could have been many other events troubling Iran's relationship with the west.

Sure, but there's a difference for the US between "conservative elements taking over" in Iran and "conservative elements taking over buoyed on a wave of anti-US feeling directly resulting from the US imposition of an unpopular, brutal regime" in Iran.
