What do Kerry's comrades from Vietnam think?

OpinionJournal.com has an article by John O'Neill, who took over command of John Kerry's swift boat when Kerry transferred out of Vietnam to the US.

O'Neill also debated Kerry in 1971 on TV when Kerry was claiming American servicemen were committing war crimes on a regular basis. O'Neill basically called Kerry a liar on TV and Kerry let the matter drop.

O'Neill does not think Kerry is fit to be the commander in chief (ie President) based on what he did after he came back from Vietnam. Not because he protested the war, but because he was implying all American servicemen were only worth contempt. Important read.
