My Lai is before my time, but I do remember his involvement with Iran-Contra.  (And Iran-Contra, BTW, really plecks me off.  How could people elect Poppy Bush after that?  Okay, we all knew Reagan was kinda senile; maybe he really didn't know what was going on.  But his VP was at the meetings!  And somehow didn't hear a thing.  And don't even get me started on Ollie North.)

But I still think Powell stayed at State when Rummy and the neocons had effectively cut him out of the administration because he hoped to be a voice of moderation.  Be interesting to see if he stays on.  People are saying that it's a bad time for him to resign, because Yasser Arafat's death has created an opening for a Mideast peace deal.
