Scott Glenn is
Donald Rumsfeld
Scott Glenn has, if anything, more claim to military experience than Secretary of Defense Donald Rumsfeld, since Glenn was a US Marine for 3 years in the 1960s, and even in the 1980s was able to do 2,000 press ups at a time. But he's rather more angular than the slightly rounded Rumsfeld, and to the best of our knowledge has never condoned the abuse or torture of prisoners.
