I do rather take exception to Bush wearing soldier suits, and I wonder why our troops don't. Can you imagine Lincoln giving the Gettysburg address in uniform? Or FDR donning khaki. Harry Truman served in the first world war, but he wore a regular suit to announce the Japanese surrender.
It makes me think of my father's story of a lawyer, who came back from the second world war, and took to wearing his good conduct medal into the courtroom. (He stopped when opposing counsel turned up wearing a Bronze Star.)
