US and IRAN

I just read a comment from Colin Powel saying that US should not infer in Iranian internal affairs and Americans should not forget that Iranian president has been elected freely. On the other hand Rumsfeld is playing another tune. The same business with reformists and conservatives in Iranian politics?
It is a matter of time. If all foreign powers specially US could stop war mongering and inferring in Iranian affairs ( something that Iranians are culturally very sensitive to) people are going to straight their account with conservative fellows, hopefully in a peaceful way.
