brick, I thought - I may be completely wrong - that news of Shinseki's departure appeared several months before he made his observations to Congress?
IIRC, at some point in mid-2002, the New York Times reported that Shinseki was to retire in 2003, and that Rummy had chosen Jack Keane to replace him (which was, of course, completely wrong), and it was taken as being something of a snub to Shinseki for his (supposed) successor to be announced while he still had some time to go, since it potentially cast him as a lame duck Chief of Staff.
His comments about troop numbers were met with a public rebuttal by Rumsfeld and Wolfowitz, who suggested that the General didn't know what he was talking about, and that they knew best...
Have I completely mis-remembered this?
