Yep. He's done a lot of "good work" for Iran ever since the revolution, a lot of amazing stuff for one person to accomplish. I use the term "good work" in the abstract sense, I mean in the sense of him serving his country and what his country wants, not in the sense of what we think of as being one of the good guys or the bad guys or what the United States wants or what the "West" wants. Some of it is common knowledge/widely known (known to anyone who's willing to do some open source research), what we've already talked about on this thread for example. Some of the stuff that was immediately post-9/11 is a chapter in "you can't make this stuff up" in the gray world where the Foreign Service/DoS, our national intelligence apparatus, and military overlap. I think there's a lot more of it that we're going to gradually learn about in the next several years and decades.
When you study the Shah's Iran (or South Vietnam in the 1950s and 1960s, or...) then it starts to makes sense where larger than life characters like this guy come from. It'll still leave you scratching your head though.
As for him being one of the good guys or the bad guys and which things he did were good and which ones were evil, if you believe in western values and things like Israel's right to exist, then...
