About Afghanistan: the CIA had been involved in Afghanistan for decades. They had volumes of information, and allies. Russian involvement made a lot of information available (spies) and set the country up for interventionist scenarios. With Iraq, the entire military had been there 10 years before. Those are not the case in Iran. It's much more of an unknown. And frankly, Afghanistan really is easier to invade, so I'm not sure invading was such a shock as you claim, especially coming a mere 20 years after the Russian invasion. It's a country divided into self-interested warlord factions. Achieving any kind of lasting effect, that's another thing entirely... but sitting around having pot-shots taken at you, no problem. Especially if you can back it up with cash. Sure, who knows what can happen. But it would practically have to be a new world order, slanted towards that possibility. So that's not a good reason for keeping a lid on any talk of Iran being unjust or unfair, just out of fear that such talk now would somehow contribute some fraction of a fraction towards intervention in some unknown, completely removed event in the distant future.
