Just saw the second part yesterday (sorry about double-posting, but this is new info). It really clarified some things about the first part, and it also explained the huge mistakes made in Iran (the CIA hadn't even heard of a Fundamentalist Islamists before and Jimmy Carter started supporting the Shah and didn't give a rat's ass about Khomeiny, which turned out to be quite an error), and later in Afghanistan, when the Soviets invaded. He basically let Brejhnev (sp?) place troops on the border, mostly because he trusted the USSR not to invade.
These errors were mostly because he had cut down heavily on the CIA's senior and experienced staff, such as field agents, not letting them gather information about the "opposing force" (i.e the Iranian islamists). He (Carter) then turned his point of view to a more aggressive tactic, telling the CIA to turn Afghanistan into a Sovietic Vietnam.
I already knew most of these things, but the details were nonetheless interesting. Especially one about how Regean was a piece of shit even before he became president; When the election was coming, and Carter was re-running for president, the US embassy staff in Teheran was kidnapped by Islamic students, which I also knew.
One thing I didn't know, however, was that someone inside Carter's own staff reported to Regean's campaign workers that Carter thought it best to free the hostages in Iran before the election. With the aid of the CIA, Regean "made sure" the hostages weren't released before the election, so that he could use the scandal against his opponent, Carter. Obviously the two ex-CIA agents who by a coincidence left Carter's senior staff to work on Regean's campaign denied it, but all things pointed to them doing such a thing, such as documents about a "Operation October" or something. Regean then turned the CIA back into a savage Intelligence organization, killing and overthrowing all over the world (many of you mentioned the details in the "Regean dying" thread, so I won't recite them here), until the collapse of the Soviet Union.
Third part next week, and it will probably be about the "war against terror".
