Reitred Generals against Rumsfeld

I'm not really prepared to comment on the ongoing story of retired generals criticizing Secretary of Defense Donald Rumsfeld, but I do have one preliminary thought to pass along. The higher you get amongst commissioned officers in the military, the more political life becomes. It appears that the Generals coming out against Rumsfeld are generally left leaning individuals. Unless they cam come up with some very good specifics on why they think Rumsfeld should resign, their opinions should be viewed very skeptically.
