You can say whatever you want about Don Rumsfeld, but he has certainly set new standards in the field of improvised politician's poetry. Hart Seely has compiled a a book of Rumsfeld poems, some of which he put on-line here and here. I only hope that Don keeps on poeticizing after being kicked out of the government. I think he is more comfortable with language than with warfare.
His poems have also been set to music, by Bryan Kong and Elender Wall (listen to some songs here), and by Phil Kline on his album Zippo Songs. Here are the Three Rumsfeld Songs from this album in MP3 format: As We Know | That Many Vases | Near-Perfect Clarity
Maybe Rumsfeld could have kept his job if he had listened to fellow poet Ho Chi Minh's words "The Poet Should Know How To Lead An Attack" from the song On Reading 'An Anthology of 1000 Poets' (MP3, here performed by Phil Minton and Veryan Weston from the album Ways Past). Unfortunately, it is too late now.
