What bother me here is not Condoleezza Rice specifically. Every ranking official of any country (or company) owns a big share of that country's sins and there are no "clean" administrations. Complicity is the price of admission and they all pay.
What does bother me is what this is a symptom of. Lets be honest about why board members are selected. Ex politicians wield political and corporate influence and a board seat is a way of renting that influence. At best its an elite club, at worst it's outright corruption but its always on that scale.
I guess that if pressed they would say that they bring experience and competence. That's as nonsensical as a large corporation justifying their political donations as an innocent, democratic expression of political preference. It's hard to say with a straight face.
Having ex politicians on a board is such a public display of stink. It's like when a politician who spends his entire life as a "civil servant" is obviously and publicly living a billionaire lifestyle with yhahts, mansions & private jets. They don't even bother to launder that dirty money. It's just displayed filth and all.
